Hello guys,
Sorry for the late reply. I did indeed check our back shop for a used two-piece 21-spline 4.70:1 input and only found a broken one (input snapped off). Sorry tx_shooter but we don't have one to sell you. Also, I'm not sure too sure about credit on trading it in... I think you'd get more bang for your buck to sell it to someone who needs a 23-spline gear set in the first place...
Wainiha, the route of going with a W59 contains the following three issues and solutions:
1.
Problem: The W59 bellhousing only fits a 2RZ-FE or 3RZ-FE engine.
Solution: You can use any 1984-1995 non-Turbo 4cyl bellhousing (G- or W-series) which mates to the 1995-2004 W59. Now you'd have a 1995+ Tacoma/4Runner W59 installed behind a 20R/22R/22R-E/22R-TE.
2.
Problem: The W59 uses a left-hand front output chain drive t/case.
Solution: You must get our transmission to transfer case bolt pattern conversion kit which changes the bolt pattern to work with a right-hand front output gear drive t/case (

3.
Problem: The W59 uses a 26-spline output which is not compatible with the gear drive t/case.
Solution: Our conversion kit above includes a coupler (at top-center of
our picture) that converts the 26-spline output to a 23-spline so that now you can place a gear drive t/case with a 23-spline input behind the Tacoma W59 transmission. Now we have a rather complicated (explained below) but do-able solution for tx_shooter.
Complications...
- This will add approximately 1/2" to your drivetrain so your crossmember mount may not bolt up (might require slotting) and you'd want to ensure your drivelines can still work with the 1/2" offset.
- Because both the W59 and anything installed down stream from our conversion adapter requires a top shift t/case, regardless of application the t/case shift handle will move rearward by at least 1/2" (if you currently have a top shift t/case) and up to 4.5" (if you currently have a forward shift t/case which will need to be converted to top shift). Worst case scenario would require hacking up part of your center console, if applicable.
So there are a few complications with this route. Alternatively, we have built custom W59/W56 hybrids that use W59 front parts with W56 rear parts (so you can directly install a gear drive t/case right into your 4cyl Tacoma without any special adapters or couplers) (we require the customer to supply both a W56 and a W59 transmission since core parts are needed from both transmissions) (if your W59 needed a rebuild anyway, then this works out in the end since a good used W56 core transmission costs less than our new bolt pattern conversion kit). However, as W56 rear parts are all 21-spline, you'd still end up with a 21-spline hybrid transmission, which doesn't help tx_shooter and would effectively "downgrade" Tacoma/4Runner setups to the weaker t/case input. However-however, we will build the hybrid using the W59 output shaft -- yes the incorrect 26-spline shaft -- and then sell only the coupler from our conversion kit to then convert the spline count at the back of the hybrid transmission to a 23-spline and BAM you've got yourself a bonafide 23-spline hybrid W-series transmission at the expense of two transmission cores and our conversion coupler
Options... Options... Options...!

edit: Wainiha, I forgot to add that the W59 is only used in 4cyl versions of the 1995-1998 T100s, 1995-2004 Tacomas, and 1996-2002 4Runners.
