Bought new fenders and running boards for my 39 GMC. I have spent the last couple nights rough fitting them before paint.
running boards- good thickness but the mounts are 1" off. Im not sure if there is a difference between the chevy and the GMC though. My original boards have mounts 32 1/2" center to center and the glass boards are 33 1/2" center to center. Also it would have been nice to have a metal mount moulded in instead of just glass.
Fenders- Drivers side was great but the passenger side has a major void in the glass at the front of the fender. I didnt realize it untill I stuck my finger clear though while aligning the fender. It took 5 weeks to get the fenders so I think I will just repair the fender rather than send it back. http://hotrodders.com/gallery/data/500/medium/27.jpg
