How many parts are interchangable, between 72 and 75? Options

[Noodles]

Like title asks, how similar are these cars? Just got myself a 72 parts car to steal the engine,wheels and few other things if possible. Would really like the hood,glass,mirrors,engine cover and eventually the motor if it's as good as the PO said it was.

And sorry for the dumb questions, I'm very new to the 914 addiction and not having much luck with the search function.

The dash, doors (and all window components), bumpers and shift mechanism are the major design changes between late and early cars. I believe that the front brakes are also different. I have never owned an early car, so I am speaking from what I have read here, and what I have seen when ordering parts. The fuel pump was also relocated up front on the '75/'76 cars.

Early cars are lighter due to the late heavy bumpers and associated shocks, etc. as well as the later doors being reinforced for side impact (a good thing, IMHO). I am keeping my late doors, but backdating my bumpers.
