couple R-154 swap questions

The 5-speed swap is getting more popular in many circles.
Here is some additional info to consider.

Input shafts lengths vary.

Pre 1995 R150\R151 = 6.5"
1996 up Toyota R series = 7.5"
AX15 = 7.875"
87-92 Turbo Supra R154 = 7.25"
AR5 = 8.2"
MA5 = 8.2"
NV3550 = 7.875"
NV1500 = 8.6"
AX5 = 7.5"
Toyota W series = 6.5"
Toyota G series = 6.5"


Since the R150 has a shorter input shaft than the Dak ax15 then a special pilot can provide the proper support. Then, does the R series mount to the Dak bell?

The Jeep/Dodge AX15 5-speed, the Jeep NV3550 5-speed, the Jeep NV1500, the Toyota R150F, R151F & R155F, the 87-92 Toyota Supra Turbo R154, the Isuzu AR5 and the Pontiac Solstice\Saturn Sky\Chevy Colorado\ GMC Canyon MA5 5-speeds all share the same case to bellhousing bolt pattern (Large Pattern). As such there are a number of possibilities that can be had when a 5-speed is desired:

If you are building a street rod then the NV series can be used, they are not so popular with the folks swapping into stock body cars.
If the NV1500 or NV3500, as used with one of the engines first listed above, is available then it can be used, trans and bell, and the same flywheel notes apply as for the Dak ax15. If the NV comes from a Jeep inline 6 or the Mopar 4-cyl then a Dak bell will be needed but the issue then goes back to the shaft length that was used and what will be required to accomodate the trans in the swap.
Since the NV1500 has a longer shaft than the ax15 we would need to consider where the splines are located in relationship to the clutch disc. Actually, if any of the trans and bells are swapped around the spline location must be checked. We can support a 'short' shaft and we can shorten a 'long' shaft but the splines are not moving.

Also, consider the Getrag 238 6-speed as used in the Dakotas and Ram1500 '05 thru '08 or so. This is a very stout trans.
