    I have a friend with an 80s 2wd 3/4 ton front end. How hard is it to adapt it to my 1970 c-10?

    in the last 2 months i rebuilt my dads '85 3/4 ton suburban front suspension, and im in the middle of doing the same to my '70 c5 blazer while adding disk brakes. im not positive but i think they are an easy conversion. make sure you get 3/4 ton ball joints and save the convex shims between the frame and the upper control arm (1/2 ton's have flat shims) . before you do anything you need to measure and make sure your bolt holes will all line up.

    From what I've read other places, the entire crossmember from the 80's will bolt onto your 70. I'm not sure if you need to drill new holes or not.

    "73- '87

    This is a bolt in swap. I beleive that the replacement parts are easer to locate. Just my .02 cents

    i was wrong, the centerlink is different somehow? i installed 1971 spindles, now my new inner tie rods won't fit into my original c-link. i have read a little and am still confused about whether or not i can use a newer c-link. if i keep my original tie rods it all works ok. does anybody know if i can put a newer c-link in my 1970 c5, or will it hit my crossmember?

    Change the tie rod ends to '71 and you might need an adapter sleeve for the rod ends,

    The drag link ends are diferent and so are the ball joints, so you would have to weld up a drag link. I dont like welded steering parts. The whole newer front suspention will bolt on if you use the crossmember. It would be less to take apart and easyer to get replacment parts.
