Unfortunately, I don't have any updates as the car for which this swap was slated is no longer around. I have the grand majority of the R&D work done, so I might just list the trans for sale along with my boatload of information and contacts.
Let me know what you have in mind, Wish. I just recently read, I think on Facebook or somewhere, that if the engine is moved forward slightly, the transmission can fit better in the tunnel. It wouldn't be necessary to cut the tunnel. I don't know how easy it would be to do this with an LA on a stock K member.
