Hi, Iím about to dive into a 67 Coupe project, and was wondering about suggestions on who to order parts through? CJ Pony parts, Rock Auto, etc. looking for all different parts from motor to wiring to body items.
The best answer I can come up with is "it depends".
Rock Auto can be a good source of maintenance type parts as in oil filters, plugs, gaskets, etc. Also some items like brakes, calipers, alternators, AC compressors, as well. There parts are not going to be part of a accurate restoration, but good to get the car running again. Others who have Amazon Prime accounts have found that they can beat RA prices with prime free shipping.
I have used CJPP in the past with good results. Many here have had issues lately with customer service, parts shown as in stock being back ordered, and trouble with returns. CJPP has had some great sales in the past, a 15% off anything last Black Friday saved a bunch on Dakota Digital gauges for my build.
NPD seems to be the go to supplier now for larger items like sheet metal and more. Many former CJPP customers are switching to NPD.
For performance oriented parts I like Summit Racing a lot. Good range of available parts and manufacturers, a easy return policy, with periodic promotions than bring down their prices even lower.
The best part of working on a Mustang is that you have so many choices for sources of parts. It is going to be up to you to determine which source is the best fit for what you are after.
Good luck, but beware we will not hesitate helping you spend your parts budget.
