i picked up a 312 and stnd, trans from a 57 merc today.never saw a merc stnd,in these years before.the tail shaft is 2 feet long.i was thinking it would be a t85 but on the side it says T89B-14.does anyone know the story on these.

I just bought a 57 Merc wagon with a 3 on the tree.

Once I actually have it in my hands I will see what the tranny numbers are and get back to you.

Its still going to be 3 weeks till I recieve it.Coming from B.C. Canada,but I will get back to you.

The stick cars with a 312 engine are listed in the books.The 368 stick cars are NOT listed in the books.

i just got in from tearing it down.still have one piston stuck but its moving.its never been apart.the crank has no dot and the cut in the crank where its supposed to be is not deep maybe.010 and rough like it was never finished.

I just looked at my Merc trans. The case is T85C-1 and the tail housing is T85C-7. I wonder if the T89 case has the wide bolt pattern or dual bolt patterns on the front face with the same internals as the T85?

same bolt pattern as the rest.

looked it up on the net should have done that in the first place.the t89 was used on ford trucks in the early 60s and is a sister to the t85.im sure it belongs to this 57 merc.this would be a canadian car so im guessing thats whats going on.anyway i got a nice 312 for rebuilding.
