Control arm bushings, offset shafts

[64G-lark]

Im working on a 1964 Buick Skylark A-body and have the front end torn down for a disc brake conversion. I cant afford the tubular a- arms so I figure I am going to have to make the best of the stock arms. I am looking for some recomindations on replacement bushings, cross-shafts, and ball joints. I have heard of delrin/aluminum, poly, and steel ones. All I seem to find are the poly ones. Who has the best deal? I have heard of a tall upper ball joint but I am not sure of the benefits and if they can be used with stock spindles and control arms. Offset shafts? Thanks
