Hey guys,
Im starting work on the body of my 67 conv. My question is im looking into replacing the front fenders and rear quarter panels, Ive seen some kits that include all pieces including front and rear valances, how  do i know which ones to pick. The ones im looking at right now are sold through mustang unlimited. Any advice woould be greatly appreciated.  

csm...any after market sheet metal you buy will need to be fitted. dont assume they're just gonna fit into place. if your damage to you old fenders and quarters isnt to bad i would consider buying sheets  and forming my own. depending on how good you are with metal shaping and welding. if the parts are that bad then buy replacements mu is pretty good with parts. another to consider is national parts depot. ask them when you call to place an order and try to have as much info for them as possible. the parts warehouses guys are pretty knowledgable and can help you out.
good luck and have fun  

I bought what I could locally. fortunately my local mustang salvage yard also sold new repops.  Buying from MU or NPD or any other online supplier is OK as most carry the same stuff from the same sources.  If you are doing a concurs level, only NOS parts should be your option.  The ford tooling parts as replacements are good as well as most of the others. I've read pros and cons on using, and not using ford tooling. Its a personal decision.  You will pay a lot for S&H if you buy big pieces mailorder (most need to be trucked) thus my decision to buy local for a little higher price.
