P/U Tailshaft housing compatibility

Hello all from Dallas TX! First post on the board. I am shoe-horning a 4 port Renesis engine, trans, and diff into a Triumph Spitfire.

I think I read somewhere that the Mazda P/U tailshaft housing/shifter assembly may bolt up to my 2004 5 speed transmission and will place the shifter further forward. Can anyone confirm this?

Not sure if it was the early rotary or the later B series but think it is the later models.

Also, can anyone tell me what the distance is from the face of the unit to the shifter?

Thanks in advance! Mike

The tailshaft in the 74-80 rotary transmissions are shorter and move the shifter forward, yes. Not just the P/U model but Rx-3,4,5 and 7 thru 80. I do not know if it bolts to the new 8 trans but wouldn't be suprised if it did as Mazda kept their n/a rotary transmissions surprisingly similar, up/back datable and modular. Don't have a trans handy to measure sorry. Miata tailhousing is as short as the aforementioned models but the shifter is located about 2" further back, and is a built in short shifter. I have one mated to a 81-85 Rx7 trans case. Welcome to the board.

Be sure to read the grassrootsmotorsports articles on their RoSpit, it was very well detailed and quite the project.
