rear suspension adjustment and starting figures

i need the factory lengths of the lower control arms and panhard bar. i have one way adjustable ones and the axle is a moser 9 inch and when i put c6 wheels on it, the one passenger side wheel doesent go on. drivers side does rub a touch i think the axle isnt square in the car. i have 2 inch spacers on the wheels and the tires are 285/45?r19.
tq arm is factory btw.
car isnt lowered either. also if can tell me how to get it to fit without beating the wheel wells in that would be great! i may just add a 1/4 slip on spacers to the 2 inch ones.
car is a 1988 firechicken gta. dont know if it matters.....

When I put my Double Adjustable LCAs on, I just matched them up to the stock LCAs I just took off.

Re: rear suspension adjustment and starting figures

I happen to have 2 pairs of spare stock LCAs sitting around.

I know my pics looks a little off at angle, but the center to center of the bolt holes actually is dead center between 19 1/4" & 19 3/8".

Re: rear suspension adjustment and starting figures

I'd dig out the spare PHB & get you a measurement on it but honestly? The stock length can suck. My rearend was offset by about a full inch on stock springs, stock wheels & stock tire sizes.

I say just adjust your PHB until the rear is centered.
