Rustbelt Blues gotcha down? Still love your 4 door GMT400, though?
Well you're in luck. I have this reproduction rocker panel with some other parts in a group deal when I thought I might end up with a Suburban. That isn't as likely to happen now. Cheapest I've seen online is $150 plus shipping. It could be yours for $100.
Located just SW of Chicago, but there's a fair to good chance it may be able to go on a GRM Express heading out of here soon.
