Rattling Tailgate on the \'88 I recently bought my first K5 - an '88 with a blown motor. I dropped in a new crate 350TBI and it runs awesome. However, the rear bed section is REALLY rusted out and the tailgate shakes and rattles REALLY bad. How difficult is it for a body shop to replace the bed and give the tailgate a new secure proper fit? Do the replacement panels found in JC Whitney and the like really work? Any advice would be much appreciated. The Last Truck I'll Ever Drive - Da K5!
