Hmmm ...
I have as yet to finish my conversion on the 62 Burban.
Two things that I have done differently.
I used 1/2 ton LCA's (because I wanted rubber bushings) and I had machined rings made to convert the lower arms to 88-98 1/2 ton LCA bushings.
Then I used the stock spindles off of my buddy's 94 1/ton.
Visually, it doesn't seem that it will have excessive camber, however I have not confirmed this as of yet.
