TIMMER, I picked up my 39 skins from www.oldchevytrucks.com. They didnt fit really well. They were actually about 1/8- 3/16 too wide. Took alot of work to get them to fit correctly. If I was to do it again I would just cut out the bottom 6 inches (where mine were rusted out) and fabbed in the section. I bought new to save time and labor but I think I actually spent more time with the new skins.
