I just bought a 1977 Bonanza with some rust on the fenders and a little on the back right bed side. I can patch the back but the fenders are going to have to be replaced. I am a complete newbie when it comes to truck repair, so I need to know if the replacement fenders from JCWhitney or other aftermarket internet shops will suffice (not a 'show' truck, just a user truck). Or do I have to search around for OEM parts...and where? Any comments/recommendations on quality of replacement parts would be appreciated.
