Well, here we go with the rear end swap.

What kind of car is this??

I am guessing later, because the plastic filler instead of lead, so I am calling 72 or newer.

Then there is the roof mounted seat belt, so now i am calling 73 or newer.

??

The green car is a 74 and the guy is just now getting started fixing it up.
You would have known right away if I had gotten the wrap around tail lights and plastic bumper filler in the pic.:D
He is building a 440/727 at his house for it while I build and install the 8.75 locker with disc brakes for him.
Right now it has a barely runs one barrel 318 in it.
He has a ton of new and reconditioned parts for it sitting in his garage for when it goes back to his house.
So right now we have 3 Darts here, a 72, 73 and a 74.
The 72 is my Wife Stephanie's car, the 73 red Dart (mine) and this green 74. (Robs)
When my buddy Mike comes over we have 71, 72, 73, 74 all here at the same time.:D
