E85 gas cap

i doubt it, but they do make yellow spray paint.
if you really wanted to use a stock cap, maybe graft the end of the filler pipe onto the stock filler pipe. shouldn't be that hard to do- some hose and a couple of clamps.
 
Yeah I didn't do it , I was going to have my brother airbrush one up for me but said f*7k it. I have had the trunk emblem on for almost a year.:biggrin:
 
No. Different threads.

You might call up your friendly Chevy dealer and see if they can get you the Fuel Cap from a 92 M85 Lumina. That would have the same thread but it would say Methanol instead of Ethanol.
