T56 install in a 68.
I don't think they are the same. To make my old rubber mount work on my car I had to make the holes longer that allow the rubber mount to bolt to the transmission. They are now oval holes. I don't know if you have space on a poly bushing to do that. If you have 3/8" or so on each side then you may be able to do the same thing.
It is then a major pain to bolt the busing to the tranny. If I were to do it again I would have just purchased a ew bushing and it would have saved me about an hour of messing around.

I have a brand new poly mount on my C4, does anyone know if I can use this on the T56? I'm at work or I'd go check it out! I only ask cause my buddy said he has a newer style mount from his tremec days that he'll trade me for the poly mount. He's now back to a C4, he enjoys his bracket racing!
BTW, it snowed today in Central Texas! Yesterday was almost 80 degrees here! Just think I drove the stang to work on Monday and today it snowing!

LMAO, that is Alaska, this is Texas! Snowed a whole 3 times in 10 years here! Sorry, we get all excited when we see a few flakes here in Central Texas! 
BTW, Darreld - any progress pics?
So many questions I could ask about this swap!

I ran into light issues. I swapped out my brake booster a couple weeks before the T56 conversion and could not get the brake lights to work again so I just left it unfinished and started the tranny. Now I have to figure it out and wiring is my weak point. None of the lights work to the tail lights so the reverse lockout solenoid will not work either. I am sure it is something simple. I just need to slow down and look over everything one more time. It seems like I have a short in the system or perhaps I blew the flasher. I don't know and I only get a few minutes a night to work on it if I am lucky.
I will work on getting some pictures from lying under the car. May not be the best but they will be pictures.
