I know of Mumbleys in Clinton Township. There's also a place on Gratiot and M-59. Truckworld?
I went to a place in Romeo/Washington Twp. a few years ago. I am not too sure the name or if they are still in business. I had some tow hooks installed on my truck. They sell tires, bed liners, accesories, etc. Does anyone here know the stores name? it's off one of the mile roads in a plaza.
Yeah, the place near Monroe is pretty cool... Jeeperz Creeperz in wyandotte has off road stuff and a shop. I have bought for my Jeep there, and I think they can get just about anything for any vehicle.
There's a dealer in Coldwater called Planet Powersports... they not only sell lifts but they also install them. They deal in EVERYTHING offroad, mainly ATV's and the like, but they do extremely good work installing lifts, wheels & tires, etc.
