Fellow Burb-Ites,
Ok I did it. 80 Malibu Frame swap under my GMC Burb.Streached it from 108" to 116".Pinched the front Rails 3" on each side and made new rails for behind the wheel wells. I'm sure some will O.M.G and some will say great and some will roll over in bed with nightmares. BUT if you get a good donor car you can do it and not even take the motor out. Check it out!
