Drop spindles and perf. shocks are available up front, drop leafs, blocks and shocks for the rear. It comes with a KA24 single cam truck engine specific but same as 240 minus the intake. Its possible to put a 240 twin cam KA or SR in one, but SR presents challenges with oil pan placement. I have an older Datsun truck with a S14 SR.
Ultimately depends on your goal/intended purpose for the truck. I can get most parts needed so LMK if I can help.
