I have run a TCI converter in the past and still have it in a box on the shelf, wouldnt hesatate one second to put it back in the car if anything happened to the Quickdraw converter thats in the car now,,,as far as that number, if it's a TCI number just give them a call and ask, or that number may be available on their web site.
I got one to go 3800 but it would not last. Just kept shredding the clutch lining. Maybe in 25 years something has changed but I doubt it. I thought it was a neat concept with a manual shift and an automatic (governor controlled) lockup.
