Mine has a modified driveshaft with stock U-joint at the rear, and front U-joint is the Toyota brand to match the input shaft. (off the donor car) I found out a couple of years ago this particular Toyota type u-joint is non-replaceable, and the whole driveshaft was meant to be replaced instead. So watch out for Toyata flanges with such joints, they are easy to spot with pressed crimps holding the bearing caps in.(as opposed to clips) I will eventually need to rebuild my driveshaft with a custom flange so I can have a replaceable joint at the front. Not a big deal, but I wished I had know that when I put the driveshaft together. It hasn't worn out yet and knowing someday it will, I check it for play regular and before trips.

: Hi .
: 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.
