Inliners International Forums General Discussion Drive Train Adapting a 1955 open drivetrain

I did do some research on this and found an input shaft, which says it's for a GMC Sonoma (sister to the S10). It also says WC transmission, '93-'95. Perfect, I believe, mine is a '95 T5.

I have a 21 tooth gear with a 26 spline on the input. I counted the teeth on the input shaft gear, which mates up to the main shaft. I think I'm gonna order a new one.

I found the input shaft seal at O'Reilly's but it's $35 for the seal only.

And I see an entire new input shaft for $60.

EDIT: checking with Dave Farwell to see if it makes sense to go with a 10 spline, 21 tooth input shaft and use my existing clutch. I was planning to use the 26 spline and have a custom clutch made, but that would cost about $125. If anyone here has any thought on the input shaft being the same or not I'd appreciate it.

EDIT2: Oh wait, I just remembered that I do have an extra 3 speed Muncie transmission which has an original '55 input shaft, I can measure and count the splines to make sure of this.
