I'll sticky ya. But you have to keep it current.
Change your title to something describing the WHOLE car and not just the engine. For instance SS parts the fit Base / LS / LT models.
ALL the suspensions are completely interchangeable. The FE1, 3, and 5. And all of their components, including but not limited to:
Strut tower mounts
The steering knuckles are no different between the models.
Intake manifold will physically fit the engine, but the L61 throttle body wont fit the manifold.
Cams are incorrect. The LSJ cams have a position sensor on the exhaust cam that extends out of the head. However, the grind of the LSJ cams and L61 cams prior to 2007 were exactly the same with different timing. GMPP adjustable timing gears on L61 cams can do anything LSJ cam can.
There is obviously much more engine stuff, and that would be a thread all it's own. I think you should stick to bolt on stuff.
Use the correct names. They are called Facias, not bumpers. Bumpers are on trucks. Facias are molded plastic covers over impact reinforcements, which is what most cars have.
Also, it's called a Deck Lid. The trunk is the empty space under it.
