clutch size

anyone know what the clutch diameter and spline count i should be shopping for for my 54 pontiac pathfinder? thanks!

 

i just cant figure it out without tearing the car down. this car is so fricken frustrating to source parts for.

 

For canuck ponchos just search parts for the equivolent chevy. I ***ume you're running a 235. Clutch would be 10" 10 spline.
Here's a link to Rockauto.

its behind a 239. i checked that link out

 

its not a 10" according to my buddy with the same car, he can't remember but he says its smaller. anybody know??
ten spline, 1 1/8" dia shaft, unknown clutch diameter.
i have phoned all over the place, studied online for hours, posted on other forums and i still can't find that dimension! i'm kind of amazed!

 

i found it!!!! i searched pressure plate for a 54 and it comes up 9 1/2" hooray!!
