sanderson DD9's with power steering?

-
Watching.
A casual acquaintance years ago had Sandersons on his car, with P.S. I believe they were the DD9s, but I wasn't really paying much attention at the time since I had no plans to do an early A back then; so I'm no help with how well they fit or what may have needed to be massaged into place.
The pictures really look like they'll clear- but man, their website couldn't have a more muddled description of what they do and don't fit... The "no gasket guarantee" is interesting too.

i've perused the tomes and i couldn't find anything definitive on the subject.

the fit seems to be coin flip of: don't be fooled and expect the same pain in the dick as everything else vs. they jumped right on and i couldn't be happier.

you're right the web instructions and notes are... well, not exactly clear. the no gaskets thing intrigues me. the factory didn't use 'em so i can see the idea there.
 
You be the judge if they will clear P.S. I got rid of my power steering mostly because I wanted better feel so went 16:1 manual, my motor isn't in yet but know I will not have any clearance problems after a test fit but here are my DD9 Sandersons and do believe I read somewhere they will clear P.S., maybe you can judge by the pictures, they are on my 360 for my 65 Dart. I do believe the DD9 were designed for that reason after the DD7 and DD8, hope

The Sanderson DD7, DD8, and DD9 header sets fit small block Chrysler 318-360 engines in various A-Body and E-Body vehicle applications. We are providing additional information to help determine the correct header for your application, along with notes on these headers and the vehicles they are designed for.

  • First, these headers are only compatible with automatic transmission applications. They can work with some hydraulic clutch setups. However, we do not have a list of compatible kits.
  • These headers require that the engine not use an oil filter adapter or use an aftermarket configuration that relocates the filter or directs the filter downward. For example, the early A-body adapter that points the filter rearward is incompatible.
  • The passenger (right side) header is the same for all three sets. Therefore, the difference between the kits is the driver-side header. This is due to variations in steering gears, steering shafts, mounts, and other components.
  • Some vehicle applications use the obnoxious Chrysler steering shaft coupler body at the end of the column, which is about the size of a small house (an exaggeration, of course, but this component is ridiculously large). If your vehicle uses this coupler, it may interfere with the header on some applications. We suggest replacing the obnoxious coupler body (generic image shown below) with a more efficiently sized aftermarket unit.
    Chrysler Steering Coupler
  • Engine location is always important regarding header fit, regardless of the engine or the vehicle. Be cautious of claims that certain Chrysler/Dodge/Plymouth vehicles require a special “location-correcting” engine mount kit to align the driveline to factory or improved specifications. Using these kits can prevent the proper fit of your headers.
  • Chrysler Corporation sometimes installed a variety of steering gear styles on these vehicles. If there is a fit problem, it is usually related to power steering gears. There are “some” instances where the specified header for the application will simply not fit. Often, this is as simple as exchanging the driver-side DD8 or DD9 header for the DD7. In rare cases, none of the standard Sanderson driver-side headers will fit. A custom (modified) driver-side header at substantial additional cost is the only solution for these vehicles.
The Header Sets

  • The Sanderson DD7 was initially designed to fit 1970-76 Plymouth Duster and 1970-74 Barracuda applications. However, this includes the 1970-74 Dodge Challenger, the 1967-79 Plymouth Valiant, and the 1967-1976 Dodge Dart.
  • The Sanderson DD8 was designed to fit the 1967-69 Plymouth Barracuda, 1966-69 Dodge Dart**, 1967-69 Plymouth Valiant**, and similar applications.
  • The Sanderson DD9 was designed for 1966 and earlier applications, specifically the 1964-66 Plymouth Barracuda, 1960-66 Dodge Dart, 1960-66 Plymouth Valiant, and similar applications.
** You may have noticed that these vehicle applications (the model years) overlap the DD7 and DD8 header sets. We recommend using the DD8 on vehicles equipped with manual steering. Unfortunately, it is not clear which header works best on power steering applications. PLEASE carefully look at the images of the DD7 and DD8 headers to determine which is best suited for your vehicle. Here, we often do not know which header is correct until it is test-fit on the vehicle. Be aware that there is a difference between the Dodge and Plymouth steering systems, even though they are both A-body vehicles.

Here's a picture of the DD9's on a 66 Barracuda from a car show up in northern CA. I'm about to buy a set myself for a 65 Valiant. I contacted Sanderson a while back and the guy mentioned that the original DD9's will fit an early A-body with P/S and an automatic. From what I understand they are supposed to fit pretty easy......

Was there a change to the DD9s that will not allow the new ones to fit? Just wondering why it says "the original DD9s".
 

What kinda sissy needs power steering on an A body? A girl?
the kind that is gonna run a 200 tread wear 225 up front with 4~5 degrees of positive caster and needs a free arm for activities because of a bench seat.

the kind that also happens to have a firm feel stage three box with fast ratio arms

the kind whose replacement steering column is a power steering unit

also, my old lady is gonna drive it. and she weighs like less than one of your legs. probably.

Oh so I was right. A sissy and a girl. Ok. lol

Same situation here- wife laid claim to the wagon, so suddenly it got power steering (bad shoulder), power brakes and AC...
Complicated the build, but got 'er done.
 
Kitty was married to a REAL prick before me.....not just a make believe prick. He was such an *** that he wouldn't fix the power steering in her 74 Mustang. So she had to drive it with a POWER rack and no power assist. So she has some forearms. lol She loves the Valiant's manual steering. Says it's easy as pie. And it is.

Well team this my barracuda and I sent the car to Sanderson’s to fit the headers and exhaust to my car. The motor is a stroked 318 to 390 with exhaust diameter of 2 1/2 all the way back.
Oh a side note I left the power steering in the car because that is factory and I’m not getting any younger so when I will need it I have it.

anybody running the sanderson DD9 shorts with a power set up?

asking for, uhh... a friend...
I am in the middle of doing this set up myself. I have a ‘66 Dart with a ‘71 360. Personally I have the Schumacher design engine mounts and with the stock ps box there was no chance of the driver side fitting. To fix that I decided to spend a bit of a pretty penny and get a borgeson box. Passenger side slid in nicely. With the new box everything seems like it’ll fit in nicely but haven’t gotten time to actually fit them in. Can give an update when I do.
 
I have the DD9’s on my 66 Barracuda…I do not believe the PS box will be an issue.

While mine has an aftermarket manual box, it had PS before. The only close encounter is the coupling between the box and steering shaft.

I still had the stock ps box that’s a size of a house at the time when I got them so at least for me the stock ps box was a major block and I also replaced my coupler with the borgeson piece when I switched out the box and seems it’ll fit in.
