Just thought I'd kind of "check in" since I've added a couple of posts.
I've got a 1972 Roadrunner, which I bought brand new in June 1972 and have owned it ever since. Was a daily driver until 1989 when I parked it. Started a restoration more or less, as I did change a few things, in Nov 2003 and it's about 95% done now.
Came with a 440 4bbl, A/T, and factory air. Galen says its one of 453 built and is #27 of the 27 he knows about. It was built on June 20th which puts it real near the end of the 1972 production run. Who knows? It may be the last 440 Roadrunner built in 1972!
Still has original drive train from front to back. Went over the engine (first time it had ever been opened up) put in Comp cam, roller rockers, .030 over pistons, Edelbrock manifold, Holley Street Avenger carb, Shumacher headers and a Mopar Performance ignition (made by MSD). Upgraded the air conditoning to a Sanden compressor and coverted it to R134. The interior is box stock with only new front seat covers, headliner and carpet. The rest is just as it rolled off the St Louis line in June '72.
I have the original window sticker and build sheet (and two others I found in it) plus the original owners manual and warranty card.
It came Basin Street Blue aka Richard Petty Electric Blue, which it is now, except I used DuPont Chroma base/clear paint. All paint/body work was done in house with only engine machine work and exhaust system done by someone else. The seat covers and headliner I had done by a trim shop too.
The front suspension, drive shaft, rear end, springs, and even the gas tank was powder coated.
The car was truly rust free thanks to Mr. Ziebart. A blessing and a curse that stuff is...a blessing as no rust, a curse as I stripped it off to paint the underside back to the crossmember. Left the rest on as it had done such a good job up to now, might as well keep it there. The stripping was done by a heat gun and putty knife. Imagine that as you stand under a car (I have a lift in my garage) and heat up black stuff until it's hot and gooey, then scrape it off, all right over you! Gahhh.....
I just put a tank of gas in...first time since October 7, 1989. (I have records of every gas fill, oil change, maintenance and anything else done to the car since it was new. FWIW in 1989 that fill up was 18 gallons and cost 20 bucks. Last week it was 16.5 gallons for $39.70!
I'll see if I can get a few quick pix in this post of "before" and "now".
This is what it looked like when I got started in 2003.

This is what it looks like now. (still have external trim and some interior panels to go)

The stock wheels I replaced with the US Indy mags back in 1973 when I was in California. Put them on a boat trailer so I'd have 15 inch wheels all around.
Here's the engine when I started.

And here's what it looks like now.

If anybody's interested in seeing some more pix of the process they can go to my Sony Image Station webiste at this url.

All in all it's been a lot of work, but considering it's "my baby" and has been since day one, it's worth it.
I didn't do the complete "as it was new" restoration as I wanted to make it something I can cruise the Sonic Drive In with, rather than something I would be nearly afraid to drive. I did keep all the things I took off just in case though.
