LMC is higher on some parts and lower on others. I would check around at all the parts places for the specific part you need. Also, I've heard different opinions on the quality of their parts. Guess it depends which part you're getting. Chevy Duty and Cheyenne are also good chevy parts places. Check my links out on my website for some other parts places -->
