1970 3 speed on a 68 273?

Yep, it's got the steel forks, the better syncro rings and beefier dogs, but besides being an overdrive, like I said before, it didn't come in an A body and it's a ***** to make it fit an A body.

Now, under that spring that's sticking up on the bottom where the side cover goes on, there is a ball bearing, about 3/8 inch. Don't loose it. That's your detent for reverse.
