Hey Joe,
What you want to look/ask for is a layshaft from a Toyota 4AGE 20V engine (old Corolla etc) - both MadMorrie & Slinkey have used them, and so am I...
Have a look at my blog posts for more info on mounting it :

and
http://mearcatmini.blogspot.com/2009/09/layshaft-bearing-custom-bracket.html
Once the layshaft is in inserted, the (custom) driveshaft lengths will end up within about 70mm of each other - whch is pretty good consdiering the standard 4EFTE shafts are ~220mm different.
I'm currently waiting on a mate to get some test pieces cut from perspex to see if the my layshaft mount bracket design is correct (before getting them laser cut in steel and welded) but once the design is confirmed, I can get 2 of each cut if you want to speed things up for you.
