if your donor is intact, you already have most of what you’ll need.

You’ll need a baffled tank, sender and fuel pump. You’ll also need a gauge cluster that will work with the donor ecm.

Tuning the ecm to work with whatever exhaust system you come up with will be necessary as well.

I’m sure there is something I’m forgetting. The bulk of the work seems like it will be wiring.

The truck came to me running so I’ll take the fuel tank and pump and I’ll pull both sides of the harness as well I’m assuming I’ll need the harness to plug into the gauge cluster or do people just cut the plug with enough wire to splice into ? I just don’t want to forget anything does anybody know if my stock 75 driveline is going to bolt in and match up with the new trans ?
