Sor shows the fine spline change in 9/73. This should fit my 10/73 then, correct?
Is nothing included other than the gears and the case? Shifters? D-shaft flange?
If this is a 16 spline gear, which is what is should be for a '74(four-speed truck), then if you have a four speed in your truck, you will be good to go. If you have a three-speed, you will need the 10-spline version, which, if this gear really came from a '74, while I have seen 01/74 trucks with three-speeds, it is not common, but it would not work with a three-speed.
I guess that if he posted the spline count of the gear, since '74 is a transition year, it would help clear things up.
Thats what I started to think..
A guy can be hopeful can't he?
You know much more than I, but I thought that transition year '74's w/4spd had 3 spd cases. Hence the transition gear that SOR sells. I checked RPM's on a transition cruiser in low range, and got that he had a 3 spd case.
OK, so sometimes I can not read, nor comprehend...
Sub text stated that it is a fine spline pto gear, which would be for a four speed set up, pre-80.
1974 is the transition year, hence the "transition gear" that makes a three speed t-case work with a four speed trans.
I do not find the combo of a 2.3 ratio t-case on a four-speed, from Toyota, as being something that is not possible, during the transition period, 9/73-1/75.During that time, anything could be possible. I have seen a three speed, jan-74 truck, have the larger u-joints, but be set for a three-speed lenght, and this was not "owner created". Some where I thought that I remembered seeing an "option" in 73-55's for the four speed..
Around '76, Toyota started installing the spacer, instead of the PTO gear... You may have one Bailey... Drop the side cover of your t-case(after you have drained the gear oil )if you really are interested...
Some silicone, and you are good to go, and know if you"need" one.
