How can I adjust wheelbase?

I got most all of the suspension stuff from Doctor Diff. He sent us what look like stock upper control arms. The brakes are his early '70s disk kit ( knuckles, spindles, disks, calipers, etc.). I guess that makes the track width a bit wider up front? The lower control arms had new bushings pressed in. Strut rod bushings and washers are new as well.

The rear end is all good to go. The new 8 3/4" centered nicely on the new springs, and everything went together very well.

I think the project for the weekend will be to see if we can move that K-frame any in the chassis. Try rotating it a bit back on that right side and see what happens. Can't even begin to try getting it onto an alignment rack until we generate a bit more clearance by getting the wheelbase measurements closer side to side.

I don't see how a k frame could be off that much , unless the car has been wrecked , or u didn't install something right !
