I have an 89 with stock axles, I have never done anything to them and as I understand 84-89 came with the non c clips and then in 90 started to use c clips. Is this true? Also I currently have an RE 4.5" kit with 32 x 11.50's I want to get the interco TRXUS tires in 33 x 12.50, any trouble in my future with stock axles? Thanks.
