PTO Wood Ruff key size

[davem201m38]

Hi all,
does anybody know the size (not the part number) of the Wood Ruff key on the output shaft of the correct (short) M38 PTO.

Next, for the M38A1 (Ex UN forces) Ramsay H-200 Winch.

Also, if anybody knows the size of Ramsey Model 200 winch input shaft Wood Ruff key, Ramsey part number 342027, that would be useful.

I've been quoted stupid money to get these from Ramsey USA (no dealers have this in UK) so I'm just going to get them from a bearing shop but will need sizes.

Simply, I have the correct M38 PTO and the drive line from a M38A1 or may-be a Militarised CJ5 ex UN. The winch from the CJ5/A1 is the Ramsey 200.

Thanks,
Dave.
