Hi. Please forgive me if this has been asked before. I could'nt find anything using the search. I'm planning on building a 70-73 Z. I already have an RB25 DET from a R33 Skyline and was debating whether or not to purchase the 6-Sp trans. that's avaiable from Nismo. I was planning to place this setup into my 91 240SX but recently had a drunk driver crash into my car while it was parked on the road. So I've decided to buy a real 240, now. My question though, is it possible to fit a 6-Sp? If so, do I need to use a custom driveshaft? Has anyone done this already? Thank you for any info regarding this query in advance.
