Last year on March 23 I had purchased a replacement carbon throw out bearing for my 1936 Standard FC from the Filling Station. It has been in the car since April last year and works great. Give them a call they will probably be able to help.
For anyone looking for 1929-37 except 1933-34 Standard car carbon throw out bearing assemblies, we have a few NORS ones in stock made by Master and Dorman years ago. They are $90.00 or $100.00 with the 2 x retainer clip. bob@marxparts.com
The trouble with using a real bearing is that it would need to be perfectly centered around the input shaft to work properly and not tear itself up. The carbon doesn't care.
I do not believe the front bearing retainers on these transmissions have any sort of a support sleeve around the input shaft to center the bearing. A new custom front bearing retainer might have to be made.
There are multiple sources for a replacement carbon throw out bearing.
Unless there is a specific issue or problem I suggest that the conversion is not worth the effort. You need to adapt a sleeve to properly support the bearing as bloo noted. Plus you need to adapt a different clutch arm and pivot. It also complicates the service issue for any future owner.
I have had no issues with the carbon throw out bearing in my ”˜37 over the 4000+ miles I have driven it the last 4 years. I do a lot of stop and go driving in town. I do not know if it is the original one or maybe has been replaced once. The car has 52,000 miles on it.
