I need some measurements and advice on how to square up my front end which is a 69 Coupe with TCP Coilover with adjustable upper arms.When I installed this setup, I took measurements off of my original suspension which obviously wasn't square. The lower arms must have been skewed to one side because when I had the final alignment done, the shop ended up having to shorten one of the uppers all the way, and left the other side centered in it adjustment.
I have already had a frame shop measure out the frame to see if it was bent as they said that it is pretty close to spec.
I am looking for these baseline measurements:
1. Length of a Stock upper control arm (1969)
2. Baseline length of the Strut rods to use as a starting point.
3. Front track width, and wheel base.
So that I can fix these issues:
1. Adjust the strut rods for correct for/aft wheelbase distance.
2. Set and Center the correct track width within the frame.
3. Center up the upper arms to an ideal length, then perform alignment as needed.
What is the best way to get the lower arms centered and squared for proper track width I was just going to take a measurement from the frame rail to the ball joint and set each side equal to each other and track width as I can.
What is the best way to square up the strut rods? I was just going to measure and adjust for the correct wheel base on each side, unless someone has a better suggestion.
This is the procedure I am going to use.
1. Put car on stands, shimming stands with boards as level as possible.
2. I have made an adjustable rod set to the ride height, to go in place of coil overs to keep the geometry correct while off the ground.
3. Take baseline camber measurement on both sides.
4. Reset the upper arms length to match a factory length arm.
5. Adjust lower arms and strut rods to center and square up the track on the front end, while getting as close to desired camber as possible (fine tuning will be done with upper arms as needed)
I'm look for any advice on this procedure or anything else you might be able to help with.
