i'm trying to figure out what size the clutch is in my 1954 pontiac pathfinder. it has the flat six 239.
 
 i drive the car every day to work and i would like to have the stuff ready to install when the snow flys. the only problem is that i cannot find any info on the clutch o.d. its not the typical chevy size of 9 1/2" its smaller but i dont know exactly how much smaller.i do know that the shaft is a ten spline shaft with 1 1/8 o.d. Thank you!

The manual I use is Pontiac Maintenance 1949-1950 Series 2000-2200, Printed by General motors products of canada ltd. oshawa, ontario

if my old memory serves me right I paid about $25.00 on ebay, It took a while to find the Canadian Version

You do have your clutch already in your car? Remove it and send it out for a rebuilt, it's cheap and reliable.

thanks again guys, ill see about that clutch rebuild. its all coming together. a guy just phoned me locally and said he has a very good condition three speed for 200 bucks. got a nos pressure plate for a hundred bucks and the engine gasket kit for 200. so far so good.

to update: the donor car with the seized engine had some great parts including a almost new clutch disc. they are as Bill said 9 1/2" with ten splines and 1 1/8" shaft o.d. (not easy to find online but they are around on ebay) so i'll use that clutch disc. the transmission out of the donor was toast but when i took mine apart i realized that it had good parts where the other didnt and vice a versa so i made a good one out of the two with some additional goodies from ebay (countershaft and shift fork nos)and chevs of the forties (cluster gear bushings, seals, bearings etc)

the hunt for parts has been tougher than i expected but they still exsist, i found an nos transmission mount on ebay. an exact match to mine. the chevy one looks like it would work but its different. basically the nos stuff saved my bacon on this job.
got the rear main seal in and done, that was intense but the worst part was removing the oil pan and trying to get it around the steering gear and the oil pickup. puting it back in was also unpleasant. i hope that thing doesnt pour oil after its full! (i was very carefull) the rope seals that came with the gasket kit were tough and fat so i had to get the upper one all soaked with oil and pull it through the chinese finger kit funnel a few times before i pulled it around the crank. also the chinese finger came apart so i learned how to rebraid the little sucker. still waiting for parts to arrive for the transmission and the dog ear mounts. one thing that i'm so glad i did is scavenge all the bolts and fasteners off the donor car into a box. now i have a whole back up set of bolts and you name it for my car. the guy who did the work on this car before me was a bolt sinner and used any length any where of any grade. being from the aircraft trade that makes me cranky. hoarding those bolts gave me a clean matched set for my oil pan and steering linkage. the original clutch was so worn down that the metal around the springs were grazing the flywheel bolts and left a groove in them all so i changed those out as well.

i flipped the ring gear from the donor to my super clean flywheel. all thats left now is rebuild the transmission, head gasket, intake and exhaust gasket, side engine mounts. ill post some pics now.

Fink, you must live in West Kelowna. I live in Kelowna but have a job site on the west side of the lake and I think I meet you every morning coming in on Hwy. 97. Cool to see you getting lots of use out of your car. Probably will cross paths here sometime.
