Welcome to the forum Debbie and Jack! When looking for needed parts, I've found that good 'ol Henry Ford are the best. Sometimes you can find a new unused part, but a good used part is also a good find. For aftermarket parts, I've had very good luck with NPD parts and service. Many folks on different Mustang forums still have issues buying from CJ Pony Parts. Others and I have found parts here on the forum by just asking.
Having a helper is a lifesaver working on these cars, go easy on the wife Jack :) Where abouts do you guys call home? And pics. We (I) need (would enjoy) you to post pics of your car, and a bit of its history in order for you to receive your club membership card, and secret handshake instructions :)
Again, welcome and hope y'all have as much fun with your 69 as I've had.
