Im trying to get a set of fourth gen panels into my 86 Camaro, Whats the best way to go about this?

Im actually doing a complete 4thy gen interior swap, just because i happened to get all the parts (seats, plastics, dash, and everything else) for free. As far as electronics go, im not that concerned, because the car is getting an LT1 and transmission out of a wrecked T/A, so i think after that swap is done everything should just plug in. but the door panels are giving me hell.
