replacing trunk lid and rear bumper

[dementievafan]

Thx for helping me on the previous thread guys, anyways i just bought a 97 328is coupe and im putting some parts together and i really need to know which parts on the other e36 models are compatible

this is what i need for my coupe
1. Trunk lid replacement, will m3 318 325 coupes trunk lids also fit on my car?

2. Rear bumper, is this only interchangeable between 2 doors? and if so which one e36 ones? can 4 door e36 bumpers also fit my car too?

thanks in advance
