I have a dana 60 ready waitin for the swap but I figured I might try the crossover before boltin it in. The question is what pitman arm do I use. It looks like the 2wd box will bolt right in. Also, where do I get that steering arm for the passenger knuckle to work in my 1970 blazer. N.C. redneck moto= If she starts to sink.......HOLD'ER DOWN!!!
