I have a 1983 2wd Silverado. Street strip truck (more strip than street). I had a TH-350 transmission with a 9in tail shaft, and I just bought a TCI super street fighter TH-350 with a 6in tail shaft.

My question is What is the best way to go about getting a drive shaft to fit the transmission?

Is there any Chevy truck that came out with a 6in tail shaft transmission that I could find in a salvage yard and just swap drive shafts?
Thanks,
Larry.

Speedway Motors can fix you up with a longer yoke for your drive shaft.

Would the yoke being longer not make it week?

I've never seen a replacement yoke that was 3 inches longer for the 27 spline trans application.

Have a part number for that?

Dont think you will find a yoke that long. Might be easier to just have yours retubed longer.

I have a friend that has one that is 59in long and the one I have now is 57. would I be able to find a yoke 1in longer?

Sure enough! I've never seen one that long and I'm even in that business

So I guess we need to know the length of the OP's original yoke?

[chevydragster83]

well I don't know the size of the yoke thats in it now. I havn't pulled it out yet. I have a drive shaft that is 59 inchs long, which is only one inch shy of what I need. The yoke is just the stock one on the th350 with a 9 inch tail shaft.

I don't know much about that kind of thing. Is there more than one size that came on them?
