My 67 Convertible originally had a YT 400 in it and for years I was looking for a 67 YT because I want to get it back to as original as possible. I just happened to find one off of this site a few years ago, although a 68, it is as close as I have come for the correct one for the car.

I have the original TH400 auto transmission, just not the engine (I have a Muncie M-20 in it now)

Thanks for the info. I am pleased that I found one and at $450. Now when I get it done up, I won't be to cheap with getting it done right.
