I measured the trans crossmember to leaf spring mount ( frame points) 52.25 rt side and 52.00 on driver side. From leaf spring mount to center of housing is 22.00 each side. The discrepancy is that the leaf spring mount is more forward on the drivers side. Shims should take care of it. I hope. Is this what you are saying?

You have the right idea. I was going to suggest taking it to an alignment shop and checking the distances between the front and rear wheels on each side, if one is less then add a shim between the leaf spring eye mount bracket and where it mounts to the chassis/unibody. Overall the accuracy of a decent alignment rack is going to be way better than using string and tape measure and will give exact locations of the wheels themselves, not the axle housing or some other part attached to the wheels. Not that those DIY methods aren't useful but for chasing a problem like this IMO it would be straight to the alignment shop first thing just to eliminate any possible guesswork or screwups in measuring.
