Ronnie, Cecil is correct, 60-62 had the torsion bar suspension up front. They were OK, but the coil springs give a better ride. The main problem with them now is that the parts like ball joints, tie rod ends, etc. are all different and harder to find, not to mention 2-3 times the cost of the later stuff. It is possible(and not that difficult) to sh$tcan the whole front end including the torsion bars and bolt up a complete crossmember and suspension from a 63-87 truck. The 63-70 trucks still had the 6 bolt hubs and drum brakes. The 71-87 front ends are a much more popular swap, mainly because of the 5 bolt hubs and disc brakes. There is some drilling involved to bolt up the crossmember and the idler arm, but the frames are the same width in this area so that's one plus. You can also get an adapter to mount the larger 70' up power steering box to the older frames. I think they may have even started using the integral ps box as far back as 68, but before that they used a separate ram which mounted on the linkage and were very leak prone. The later integral units are much better and easier to adapt. Also, if the truck has a manual trans in it now you would have to come up with a rear trans crossmember, they supported the manual trans under the bellhousing. Best of luck if you get it.
