    Chevy1925 (James) Truck/motor build

    Oh trust me I know the struggle. Only place I trust is an hour away. I tried someone new in town for The Limo and their alignment rack is off, not even sure how that’s possible. Found that out after I took my vette there.

    Cheapo Amazon LED headlight bulbs

    Nineo does really well in a reflector housing and they’re priced well. I run hikari in projector housings. Look up bulb facts on YouTube. He did a lot of testing

    Bought, wrecked, rebuilding a 2009 LMM

    Sounds like an issue with the databus. One time while driving an LMM I had to clear codes and my V2 came unplugged during the process and everything went blank but the truck still ran. Pulled over and shut the truck off to get everything to come back on and truck wouldn’t start. Nothing had...
