Ron,
I would be interested in getting the name/kink to the company you came across that produces the bell-housing that mates to T5, T56, or Porsche TA units.
Also, as some others have pointed out, there are a few companies that produce very close (virtually exact) replicas of the XJ13, one located in the U.K. and at least two in the U.S. During my search for an XJ13 replica, I did not come across any XJ13 kit offerings, hence my recent venture to produce such a kit.
I’m planning on adding a GT40 to my list of personal projects sometime in the future. I posted a
photo and video clip (3.3 megs) of my ride in Peter Ransom’s GT40 while visiting
GT40 Australia . I got hooked!
Best Regards
Rich
