MSD ignition installed, now I'm thinking transmission time?

Wait awhile to do the auto OD conversion. Quick time is in the process of making slant six SFI bellhousing adapters. The first one will be for a T-5 trans, which should be available in about 4-6 weeks. The next will be for the Mopar 3, 4 and 4OD manual trans. I was told they will have a belhousing available to bolt a GM 4sp auto OD trans to the slant six. At this time I don't know which trans. The GM trans should be a better fit in the "A" body trans tunnel, then the A-500 trans. Eventually, since their bellhousings are "modular", you should be able to put almost ANY trans behind a slant, including a T-56, Lenco, Jerico, etc.
