ok, in the disc brake swap thread many guys said i could use 73-87 front Lower Control Arms and related brake parts to get a 5lug with disc brakes on my 66 c20. i got 74 donor LCA's but am having a problem figuring out what to do now. Today i removed the stock brake parts and when i went to remove the stock LCA's i realized they are drastically different than the donors. the donors have U bolts and a round shaft, the stock ones on my truck are attached with a large square shaped shaft with bolts not U bolts. how do i mount the donors to my truck? is there another option?
