I built a 87 D150 with ladder bars and if I knew then
what I know now I would have put a 4-link in it.. your
gonna have a pretty lame weight balance on a pick up
and the 4-link will help cover it up.. my truck had
a decent 60' with a 1.38 but a 4-link could have got
it better... you have to make up for the weight balance
