I'm actually going to do exactly that. I contemplated dropping $4250 on Werks, but I just can't bring myself to invest that kind of money on a transmission that I can't very well work on in the future. I'll be doing an F35 to F23 swap. There's another forum discussion on this that covers the swap in great detail. parts can be found for that transmission, and including a new 0 mile F23, It will cost me approximately $2k, including a new Quaife LSD. Now I just need to sell the LSD I already have for my F35, further cutting down on that expense.
