How do you get a Suspension to hook, when the track surface is marginal at best

You might want to have close look at that 8 3/4, to see if it's twisted and lost pinion angle. Seen that happen often, especially with one used for a long time.
I haven't noticed anything, but like the rest, time to get the magnifying glass out.
I didn't want to hear that! but thank any ways.:(:D
