I will say some bad stuff about LMC, they sell some of the cheapest ******** I have ever seen. My bad experiences outweigh good ones, I would never order a body panel after some of the stuff that showed up.
-The "Reproduction grill" for my 85 was around 300 bucks through LMC, I found pretty much the exact same thing for 30 bucks on Rockauto.
-Wing window rubbers I got through LMC lasted about a month before they started cracking and dry rotting, they actually look worse as of now than the ones I replaced that were almost 30 years old.
-Just recently I ordered a new coolant overflow bottle for my 90 and they showed a molded overflow hose coming out of the lid, I ordered the overflow hose as a kit and what I got was a piece of regular hose I could have spent 2 bucks on and a couple cheap hose clamps
The good stuff I got-
I ordered a oil pressure gauge for the 90 SS and it was an actual GM reproduction part, I most likely way over paid for it.
