65 c10/ 67-72 compatibility?

[mookandairin]

So it has ben a while since here been workin a lot and I mean a lot but I found a little time to work on my 65 c10 short box step side.
I want to install a 4 link back half with coil over's in it to handle the power I am laying down these days and I want a big tire truck for the strip. Now with that being said, I am having one hell of a time finding a welded 4 link frame kit but I have found them for the 67-72's quite a bit. I know they are very close and not that far apart frame wise but I just want to find out from the experts and BAM! here I am in the right spot asking. So,
Will a 67-72 4 link back half frame kit fit like it should under my 65?
