The "proper" way to do it is to raise the engine moints also, so the engine stays at about the same angle. When I did mine I just raised the rear...which is why my rear drive shaft now hates me. If you go this route you may need to ship your axles to correct for driveline angles, or switch to a CV style shaft, but you may need a new shaft anyways because of the length thing, so that is not such a huge deal. Righ now mine has no lift, but a flatbelly and stock driveshafts and both are barely hanging onto life. This summer it is getting Chevies, RUF's, square front shaft, and homemade CV rear shaft made out of a front CV section and the stock rear section. Another thing to keep in mind is that alot of these guys who have flatbellys also have body lifts, so they are able to get away with a lot less cutting and being able to raise the front mounts more if they go that route without hitting the hood. I hope that helps.
