I have recently started to plan out what to do next with my ‘73 Duster. I plan to install an Edelbrock Pro Flo 4 fuel injection system and rebuild the 904 that came with the Duster. I plan on getting a more heavy duty rear end, but want to keep the 5x4 bolt pattern that it currently has. Is this possible? And what would be the easiest way to go about doing this? Any help is appreciated.
 
66-70 B body 8 3/4 rear might be more cost-effective. They're only a little wider than the A Body version, and a bit cheaper. The spring perches need to move in about 1/2" per side. A body rears are scarce and pricey.

Oh, welcome to the forum.

If you go with an 65-72 A Body 8.75, you’ll retain the 5 on 4 pattern. Just out of curiosity do you have front drum brakes with the 5 on 4 pattern? I suspect you do since you’re asking about retaining the 5 on 4 in a HD rear end?
 
This is getting personal, very individual. Why do you want FI? Why the bigger rear end? The rest of the car is basically stock?
 
You asked the easiest way to do the rear end - that would be to find an A-body 8 3/4 that bolts right in. As has already been pointed out, they are not easy to find, and usually command a premium price.

At the low-buck end and still pretty easy end of the spectrum, you could get a Ford 8.8 (late 90's Explorer is ideal) from a boneyard - they have a 5 on 4 pattern. They are relatively easy to shorten to an appropriate width (tons of videos on YouTube), and you can get hunt for your choice of gear ration, find a limited slip unit, and get them complete with disc brakes.

explorer has 5 x 4.5" not 4"

as stated easiest would be to find someone upgrading their axles pick up the stock a body axles ( 5x4" ) and have a B or E body housing narrowed for the axles.

Yup, you are right - I caught that after I hit send.
 
Hold on. You have a 73 Duster. That should be a big bolt pattern car. Are you sure you have small bolt pattern Wheels?

I guess some /6 cars had small bolt in 73.
 
If you do end up having small bolt, than an 8.75 A body rear would be the way to go. Just watch out for the A-holes trying to get $1000.00 or more for them.
 
The car has a front disk brake conversion kit with the small bolt pattern on it. I just wanted to save money on buying new wheels.

Yes, your correct I have a 73 six duster parts car and its small pattern 5x4 .
 
then why swap the rearend ?
that slantie isnt going to hurt it, carbed, injected, blown or otherwise
 
by the time you add fuel delivery going with the Edelbrock Pro Flo 4 fuel injection system your going to have a ton of $$$$ invested I would spend the $$ first on upgrading the rear to something with LGB the front brakes are pretty inexpensive to do presume you have 14" wheels which should be upgraded anyway IMO tossing $$ in the wrong order
 
I can see how it seems I’m working backwards. When I first got the car the main objective was to get it street legal and that was all. Now I want to make it daily drivable reliably. I’ve already upgraded the front to disks a few years back.

why the Edelbrock Fuel injection and not Fitech or Holley Sniper I have been running the Fitech for 3 years with no problems less $$ basic same result for a daily driver
 
Ah. I misread your bolt pattern when I sent my reply. As built - A bodies w 4 wheel drums have 4" bolt pattern through 76 I believe, as a factory disc car from 73 to 76 would have 4.5". I was confused.

Unless you love your wheels a whole lot, find an F-M-J body or 73-76 A body disc setup and go to 15" wheels when you upgrade your axle. Someone will buy the disc setup you have.

If you want to save money, get a Honda Accord.
There is no such thing as saving money in this hobby.
 
There’s a fine line between between being foolish with your money and using it wisely. Point is, you don’t need to worry about financials.
 
Also, I’ve been in the Diesel Engine and Heavy Equipment repair field for the past seven years, I understand what a hobby like this can cost. Don’t need any “smart” remarks.

Nothing smart intended. Just trying to keep it real.
If you are here to save money, get out while you can.
Does your credit card have the thin black stripe or the thick one ? :)
 
I’m actually furloughed right now. I’m not usually so uptight haha.
