I bought My bed parts from Mar-K and they are the best parts I have gotten for My truck a 52-3100 if We could just get an American company to start making the other parts We would be in great shape , with that said ,the body parts all need to be fitted just takes time , I just started building My truck in march of this year and My bigest learning curve was the sheetmetal and My truck needed alot of it , I had to teach Myself how to mig weld and SEE how the fitted part would look after it is done I also got into fabing some of My own parts , I built My own brake and got a sand bag from My Son to hammer curves into some parts Myself . And You'll get alot of help here on the Bolt .
