Want to guess whay my car is crooked?? (backhalf job)
I pulled the stock k-member out of my 87 Mustang today. The car is already backhalved with a 4 link and 32x14's. I've had the rolling chassis for about a year now and have just started to do some real work to it.
Anyway, before I pulled the k-member I took some measurements to make sure the car is square. I first pulled a measurement from the front 4 link bracket on the frame rail forward to the zerk fitting on the lower ball joint. I did this on each side and both measurements matched perfectly.
Next, i pulled a measurement from the front 4 link bracket on the frame to the zerk on the opposite side front (X measurement). My pass rear to driver's front measurement is 5/8" longer. I know it's correct, I measured it over 10 times to be sure.
Here's what I found. It seems that the rear frame rails are not centered in the car. They are offset to the pass side 1/2". Other than that everything looks OK.
I don't know much about the car. I bought it out of Ohio early last year. I gave it the once over at the truck stop when I picked it up from the seller. it looked OK then and still does, just looks wierd when the tape is put to it.
I do know that the Fox chassis cars have the drivetrain offset to the pass side a little. Anybody know how much? I'm curious if the chassis builder that installed the rear half offset it to match the driveshaft instead of centering it.
I haven't called my chassis guy yet. I'm sure he'll be thrilled. The car needs to be recaged anyway so if I have to move the rails around it shouldn't be too big of a deal.
I'll have to check the measurement from the tire bulge outward to the edge of the quarterpanel to verify this once the car is on the ground. I found the 1/2" offset by measuring from the factory rocker panel/floorpan seam to the C/L of the 4 link brackets.
Let me know what you guys think.
