All on a 77 TA.
Guys, I'm preparing to get a new moser rear end, DSE quadralink, mini tubs, and new 18" wheels that are 12" wide. I'm gonna put 335s on em pf course. I'm wondering what I should all be measuring and checking. I want to make sure I don't miss any of the "measure twice" steps before I "cut" because the axle and wheels Re going to be made to the lengths and backspacing I specify. I want a deep dish look. I'm getting the year one billet snowflake wheels like on their BRE US and I want the car to look like that in stance and with the deep dish wheels. I believe its a 4.5-5.5" backsppacing according to what year one has told me. I'm also looking for nominal dimensions on the track widths of these cars and how much I need to shorten it. My plan was to measure the rear axle's mounting surface to mounting surface of the wheels, measure the disrance from the outside of each frame rail to the outer fender lip (I plan on rolling the inner fender lip), and finally calculating where my 12" wheel needs to sit to not hit the fender and have the 4.5" backspacing. Id center the wheel in the space between the frame rail and the fender lip. I want the 4.5" backspacing, matbe 5 or 4.75" for that really deep look. These facts and calculations could tell me how long my axle needs to be. Is this what u guys all do? Is there a standard I csn hust go by since this has been done so much, so I can save me and my wife from having to plumb Bob and measure a bunch of crap? She gets cranky when she has to help too long.
I was also gonna do the same thing on the front to see if I can get a 10" wheel on the front and where the backspacing would be to keep the interferences to a minimal. This sounds like it's not possible or a huge headache though on these second gen fbodies.
Also, I have heard that the rear in these cars is not centered but is towards the passenger side by some dimension. I can see this on my car. Has anyone left the rear end not completely centered to keep the driveline all the same, but then shortened their PA axle by 1/2-1/4" to make it look like the rear axle is centered in the car? I have recently been advised against this as it also requires off centering the suspension mounts, but since it's going to be a custom quadralink im not sure if that's really an issue.
So, what steps do I all have to go thru before getting this work done. I think I know what I want, but I've been spinning my wheels without spending any dollars to try and absorb as much info as I can so I get exactly what I want and do this right without missing any crucial measurements.
This pic shows the car and some of the features I planned on paying special attention to.
