McCormick W4 throw out bearing

[DelValCub]

Quick question, does anyone know if the throw out bearing in a McCormick Deering W4 is the same throw out bearing that was used in the Farmall H. I know that the same engines was used for these tractors and the transmissions are the same except for gearing. Any help on the issue would be greatly appreciated.

Little bit tougher question then I thought.

I tried running W4 parts on the part look-up to compare against the H part #. Couldn't find W4 parts listed but I only checked one site.
I think they are the same but I can't say for sure so no answer is better than a wrong answer.
