Wheel alignment

[RyanC]

So given my G a drive for the first time in ages today and in a straight line under load it's all over the place.
I'm doing my tracking next week.
If anyone has any figures to hand like wheel base measurement, camber etc. Was gonna just try set it up as it would be factory and go from there. Anyone with stage 3 frames played around with alignment?
Also has anyone used toe/camber correction plates on the rear. Or camber shims to correct the rear?

Thanks
