Are you asking about the A535 (87-92 Dakota) or the AX15 (92-97 Dakota) or the one after that (I think it has an integral bellhousing)? Answers might differ depending on who's running what.

I've not measured one, but the A535 that I've seen looks to be similar in size to the T-5 as used in the Mustangs.
