Positive camber w/disc conversion

[civltruck]

I've got a 69 C30 Longhorn frame that I'm turning into a Ratrod. The cab and bed were completely rusted. The truck had "normal" camber with it's original drum brakes with about 3/4" of shims. I got spindles off of a 74 C20. Now I appear to have a positive camber issue on the right side only. The left looks just fine with 3/4" of shims. I took out all of the shims and it still looks positive. I got drop spindles and it still looks positive. Will the offset upper control arm shafts work to help correct this issue? Thanks.
