Hi everybody,
Hope ya'll had a good weekend. Like a lot of folks on here I've been trying to track down and eliminate a vibration. I just had the driveshaft shortened and balanced and my buddy is telling me I need a new transmission yole. The current one has some pretty significant worn spots on it. So here's my problem. The yoke I currently have is a 25 spline. Its 2.381 inches between the "ears" and the holes in the ears are 1.058 inches in diameter. I talked to Brian at National Parts Depot and he said he had 6 different yokes that he sells, none is a 25 spline.

My car is a 65 with a 66 289 motor, and a 4 speed toploader. I don't know where the toploader came from. Does anyone have an idea where I could find a yoke that would work for me?

As always, thanks for the help,
Brian

Are there any custom driveshat places around you? If so, that's where I'd go.
I'm lucky my neighbor is a driveshaft expert!

To preclude a wild goose chase....let me suggest quadruple checking the spline count....it'd be very easy to miscount even a few times.

I'm not sure, but I think 25 spline slip yokes are for very early Mustangs, and not applicable to toploaders. The only application I have is for a six cylinder 3 speed, 1964.5-1966, not a toploader.

Thanks guys,
The car was originally an I6 with a 3 speed. I figured the yoke would have to go with the 4 speed thats in there now though. Is it possible they changed the transmission somehow to match the yoke instead of the other way around?

Thanks again,
Brian
