doublers on a v6...

[golana]

well, ive got a 3.4L swapped in, but my 1994 4runner originally had the 3.0. it used the electric speed sensor, instead of the cable... my gear driven transfer cases use a cable... what have people done for this? the 3.0 t-case i pulled the electric sensor out of was setup for 4.88 gears, and has a 6-19 on the plastic gear on the end... my gear driven cases havd a 6-20 (i think) on it, and was set up for 4.10 gears... i would like to keep the electric speed sensor, but i dont think that the gear driven and chain driven t-case speedo gears are the same... the v6 has splines, and IIRC, the gear driven 4cyl has a channel cut into it that a ballbearing fits into...

thanks in advance!
