I test drove this 82 k5 and when you stick it in 4whl low and stick it in D it sqeaks ? Whats going on, what do you guys think is the problem? It seems like an OK deal but the body has alot of rust and alot of rust holes in the back and fenders. It doesnt have any tow hooks, a bent grillguard, 33" mudkings. Hes asking 2500. Is that an alright deal?
