My shaft is also 23 spline. Maybe my problem comes from looking at the TR6 driveshaft I was using. It has wayyyy bigger u joints than the stock GT6 or the Toyota shaft. I haven't really gone to any driveshaft places yet but that may be a future option.

: Hi PJ,
:
: My project is in another city, so I
: can't rundown to take a look, but I
: thought that although the Toyota
: driveshaft was a little smaller in
: diameter, the universal joint was a bit
: more substantial. I was planning to
: have a driveshaft shop do it up for me
: per Dan's instructions. Even with some
: performance modifications to GT6
: engine, I think it'll hold based on the
: performance numbers for the 4AGE engine
: (115hp/100ft-lbs vs. our
: 95hp/115ft-lbs).
:
: How many splines does your coupling
: have? If it's 20, your drive shaft
: "might" be a slightly lighter
: weight than mine (23 spline), but I
: don't think I've ever read of Toyota
: upgrading the shaft along with
: strengthening the tranny.
:
: Acceleration ought to be a blast with
: that 3.59 1st gear vs. our 2.65. It
: will be as if we put a 4.50(!)
: differential in the car.
:
: And the higher .861 fifth gear will
: seem as if we put in a 2.82 diff. RPM
: at 80mph will be 3010 vs. 3490. I
: "love" these numbers!
:
: I am really anxious to hear how it all
: works out for you - my car won't be
: completed and driveable for a couple of
: years yet.

: Ciao! - Jim M

: Hi again.
: I am finishing up my Toyota T50
: transmission swap and I would love to
: know what other people have done with
: that tiny little front U joint and
: input flange?? It looks rediculous
: compared to the TR6 flange I had in it
: before. Thanks. P.J.
