Do you call it a barn find if you're the one who drove it into the barn and parked it 30 years ago?

I bought this car when I was in high school more because of how excited my dad was about it than for myself. My dad bought a '71 340 Duster after he got back from Vietnam and he really loved that car. But young wives and babies, right? But when he saw this one sitting in a yard for sale, it take much convincing and I was in.

We rebuilt the 318, but it's nothing to write home about. It has some TRW flat top pistons and a TRW cam with a 650 spread bore Holley. We put a shift kit in the factory auto and a slap stick shifter, but it still has 273 or whatever airplane gears it came with. It was originally yellow, but we painted it green like my dad's 340. It sounded alright and ran good enough for a high school kid who grew up on Fast Times at Ridgemont High and stories about his uncle's and dad's muscle cars. Unfortunately, it has a leak (I think it's probably in the cowl) and water runs into the floorboard every time it rains. That was a little beyond our abilities at the time, so I parked it in the barn and it became one of those things that we were always going to get around to. But we never did. I lost my dad to pancreatic cancer a couple of years ago.

A few weeks back my 16 year old asked me if we could get it out and fix it. He's finished a year of collision repair at the tech school and worked full time this summer at a local body shop. And my skills are a lot better than they were back then. So, the prospect of pulling the dash and tackling this doesn't seem as daunting as it once did. If we can get a few to-do things checked off the list over the next couple of weeks, we may pull it out when the weather cools down and the snakes quit crawling. Maybe see what we can do with it this winter. I came across this forum while I was doing some research, and it seems like there's a wealth of knowledge here. I hope this turns into a full blown restoration thread and not just a forgotten post somewhere down the road. I guess time will tell.

Here are a couple of pictures as it currently sits. I guess one of the first things we need to do is see if we've got a trailer sitting around that we can steal some wheels off of to get it into the shop.

You came to the right place. This forum is chock full of gurus that can steer you in the right direction. Good luck with the project, it will be a fun ride when you get it going.
 
Welcome to the site!
The water leak may not be as bad as you think- more often than not, the wiper pivot seals have long since rotted away and that gives you the leak. Or leaf-plugged cowl drains will do the same thing. Once you get it out and cleaned up, you'll be able to run water over it and pinpoint the source of the leak before you tear into it and have a "DOH!" moment.
 
Looks like a great project for you and your son. Clean out the junk and get after it! Good for you for keeping the car that long! 65
 
The squirrel found it before you did.

And kudos to your son for not getting sidetracked by the ATARI 2600 on the hood lol.
 
Welcome! First two things you'll need are a tow rope and a garden hose :)
 
The barn looks to be in rough shape as well. Good idea getting it out from there, then a leaf blower and face coverings appear to be in order. Hey! It even has a fender tag!
 
Yep, probably is the wiper pivot seals. I have put cars away and never got back to them and then sold 20 years later. I usually get a call or text saying how easy it was to get it fixed and back on the road...

I'm going to start there. I guess I'll replace those and then hit it with a garden hose and see if that does it. As I recall, it was the worst on the passenger side. But both sides may have been leaking.
 

Welcome. I think that qualifies as barn found. Even though it’s your car and your barn and you put it there, It’s still barn fresh. It’s nice to hear that your son is interested at 16, and you guys are going to build it together. Get out there and get his hands dirty!
 
You should buy the factory service manuals as soon as possible.
An example from eBay:

 
Yeah, I think a full rewire with a new harness may be in order, But, dang! Those Painless kits are expensive!
There are reproduction harnesses available. They just plug in! See if they make them foe a 76. I know they do for the 74's

Thanks for that. I just picked that up.

I'm going after work today to pick up a 46RH that I found on marketplace. And I might have a lead on a rear end. I've just got to decide what gear I want to go with using the OD transmission.

Just so you know- the 46RH isn't a simple "bolt in" swap. Clearance issues for the OD unit make for some interesting necessary modifications.
Although it names the 42RH, the OD issues are the same with a 46RH- this thread will give you an idea of what you're up against:
42RH / A-500 in a Duster with pictures.
 
3.55 with that OD is a good gear, had that in a 5th ave I modified....if you want OD and not have to cut the torsion bar crossmember, go to a manual with an A833OD....
 
haven't a few on here adapted a gm th2004r od trans? they're small so don't need tunnel mods.
neil.
Yes, Lonnie from extreme automatics has a kit to stick a 2004r behind a small block Chrysler.
I use a 3.55 gear with a 46RE in my D100 and it’s an awesome combination.
