mini tub diff width

[Rybar]

Gav I think most guys run 54"-55" wide. I would cut out the tubs, mock of the wheels (IE how far out you want them to sit) and then measure.

Ryan , i thought you would narrow the diff and then order rims to suit with the right backspace? also is that measurement from the diff flange to flange or wheel mounting pad ?
Im confused on how to go about this,, what comes first the chicken or the egg?

hello Gav like Ryan said if you dont your rearend yet get your wheels first with the look and depth you want then order rearend but remember to measure fro wheel mounting surface to wheel mounting surface and add for thickness of rotors,look at mine if you like that look I can give all of the measurements or can change to get the depth and look you like,let me know I will be glad to help.

That would depend on your build. If you are building a rear end anyways, choose your wheel first with your dish preference and start fitting. It's best to measure your car because from experience no two cars are alike.

Being new to the PT build I'm presume there are many ways to get the results each person is after. My understanding and the way I planned my build was to do the mini tub while I was replacing quarter panels, assemble an install my rear suspension set up, then measure and order the rim & tire combination to fill the big hole I just created. Is that not why I'm going to have to order a set of these super expensive PT type wheels I keep seeing on these builds?

, so how do i work out my dish or backspace without a diff to measure from? Im after maximum dish i can run..with a 12 inch rim.

I had a measure of my diff today ,, its a tru trac moser ,, it has big drums,, did they use ford rear brakes on some of these? Im sure i saw a ford logo stamped into the backing plate somewhere when i purchased it? will that be a factor with getting rear discs or are the axle flanges the same stud pattern?
sorry i got a lot of questions here ,, i also thought narrowing each side 2.5 would bring the saddles very close to the axle flange..

If you want to simplify things, have moser weld on Chevy housing ends on. Pn 7900 or 7900FM (flush mount). This will allow you to use your parking brake backing plate as a bearing retainer depending on the disc brakes you run. The 7900 uses a large press on ford style bearing so that eliminates the c clip. If you already have your rear end and need to narrow it, you can cut off the ends and replace with the 7900's. You can get your axles cut and resplined and change the bolt pattern to Chevy 5x 4 3/4.

my 69 camaro has 55 inch rear end wheel mounting surface to wheel mounting surface that's 5 inches shorter then stock wheels are 18x12 5.5 back spacing fits perfect in my car
