2007 rocket black frontend are they any measurements on squaring the rearend and if so what are they and were do you start thanks 1x

[Rocket up top]

Lrt 18 1/4 Rrt 18 1/4

Lb 15 Rb 15 1/4

lrt short rod 16 3/4

side to side measurement 2in frame 16 1/2 . 1 3/4 frame 16 3/4

those are standard rocket bar lenths that will get the rear where it needs to be .

i feel u man. i've been down this road and it's a dead end. you can go to the trouble of truly squaring the rear end, but the fact is that the axle (lateral) relative to the frame (longitudinal) is always changing as you are racing - assuming you are running a standard 4-link, it's what they are designed to do. unless something is bent, go by the rod lengths. not only that, a lot of chassis are designed to "dog track" or are in yaw when they are actually going straight. that's when it really gets confusing. This is a case where close counts and you have to ask the question, "the rear end squared relative to......what?". i'm not saying it's not important, just don't spend dollars making pennies.

I believe thr Rrt should be 18 1/2. That is not square, but the recommended starting point.

My baseline is to the right more with the rear end, 15 3/4 for 2 in cars and 16 for the 1 3/4 car, the reason is to free up the car.
YMMV
