As already mentioned, there is more to this than just the engine. That said, the LA is pretty much able to be bolted to the enginr mounts. If an OE-ish trans is not used then the rear is likely going to require changing to a later unit. If he wants to keep the original rear, then the best bet (IMHO) is to go to an AAJ Brakes rear disc kit with e-brake. Bolts right to the original stuff. I danced with the idea, some time ago, of an electronically controlled valve boy activated by the original buttons in the pushbutton control. I have NO idea how feasible it was, though...
