Thanks I'll look into those. Summit does not have the 1" like these and at $200 for a pair, a good deal. I think the PST ones are clocked a bit for lowering, not sure these are but likely it does not matter.
 
GoldOne Just came across your build. These are a bit late for you to use but maybe someone else having a wheel fitment issue might be interested. Here are a couple links;

Nice job on your build!

Thanks. I considered the 1st one, but ruled it out since it does not help with axle width.

I was assuming the price is for each bar. It's not clear in the ad. The pic shows 2 but the description says "bar" not bars. I posted a question on Ebay.
 
I've settled on 49 5/8" planned for the disc to disc diff width....

The 8.8 I'll be using has a 2" pinion offset to the passenger side. Since these cars come with a similar offset (something like 1 3/4") I'll likely take the same off each side. The 8.8 is 59.5" disc to disc, so that will mean 4 15/16" off each side. The minimum cutoff according to Dutchman Axles is 3.5" so I should be fine.

Some revision: For simpler calculation, I've adjusted the D to D width to 49 1/2" That's an even 10" off the 8.8. The A Body offset is 1 3/16" to the passenger side according to Dutchman and confirmed with a measurement. That's more difference than I like so I'll be going with different cutoff amounts. To adjust the 2" offset closer to the 1 3/16" mopar setting, I'll move the center over 3/4" to the driver side. The passenger axle will be shortened by 4 1/4" and the driver axle by 5 3/4".

For reference the length of the 8.8 tube outer to outer is 56 1/4". Dutchman requires this measurement.

Edit: What they want is backing plate outer flange to flange. Edit: It measures 54".

(Boring stuff, Its just handy to have the numbers here for reference)
 
I suspect these are in my future. My guess is I can unload the 340 bars I was planning to use to offset the cost.
 
So 44" cut down? What backspace are your wheels? I'm finally going to be sending my rear off to get cut but I lost my spec sheet so I need an idea of where I was. I think I'm supposed to be 54" axle hub to hub
 
Rear are 18 x 10 with 4" backspace. The tube projects out another 1 1/8" past the mounting flange, so 2 1/4" total extra. Measuring that way I'd be at 46 1/4" to the outsides of the axle tubes.
 
OK so me being a 20x10 6" backspace my rear end should land 4" wider then yours overall. Your at 44" housing end to housing end?
 
I'm at 44" to to the outsides of the backing plate flanges. Housing end to end is 46 1/4". Adding 4" of backspace would put you at 50 1/4".
This setup gives me 1 1/4" from tire to frame rail, and with the diff near frame bump stops will give about 1" to the outer fender well where it curves in. I assume you will have to trim that area out for your setup.

Are you using an 8.8? If not of course these numbers will not apply. We'd have to use mounting surface numbers, which for me is 49.5"
 
Mounting surface works for me. At that math I need to be 53.5 not my current 54.5 which explains a ton to me.
 
I'm way tighter to the outer wells then I recalled being during mock up. Of course I only mocked up one side.
 
I've got too many scraps of papar floating around and CRS so I decided to use FABO for keeping track of the numbers. Kinda handy to get at it with the iphone when not at home.

I've also become very handy with the EDIT button while its available :)

I think your tire is taller (I'm at 27") and with your coilovers you'll be lower so I imagine you will have to chop out the outer fender wells.

Going through this last night and what no I found my sheet with my measurements. Mounting surface to mounting surface should be 53.5" like I thought yesterday and I rechecked it today and my mock up axle is at 54.5" so I need to blast off another inch not retub my car.
 
Just out of curiousity, do you have your tire's section width and height handy?

I don't know how close these cars are in the frame and quarter dimensions so I'll throw these out there.


frame to frame (wheel side) - 38 7/8"
quarter lip (inside) to lip - 67 3/4"
lip to frame - 14.5"

I'm 14.5 lip to frame on the car I do not how ever have the total width handy anymore.

11.7" section width
9.5 tread width on a 10" measured rim
29.3" diameter.

My mistake, the price is for 2. That's the best I've seen.

If you haven't bought t-bars yet, with being a member here you get 10% off purchases of $200 or more so the 1.03" bars would actually be $197.10 and free shipping. Just something to consider.

Thanks

Yup, I'm aware - thanks. Maybe I'm a little brain dead reading the ad on Ebay but I suggest you clarify that its for 2 bars.
 
Not much work happening but I'm collecting parts.
Should be interesting to set up a differential.
The axles are at Dutchman for shortening.
