Hi just see this post and I’m a tad confused, now I’ve stripped down my 1945 headstock and reading the manual and parts list it shows 000806 (std806) and 000805 (std805) so I take it 3 of one and one of the other as the manual says 3 are the same but my 1954 says 012620 and 000805 (std805) so are 012620 and 000806 the same? Does my 1954 need 3 and 1 like the 1945 I only ask as a listing on eBay says all models and lists all 3 numbers in the kit.

Cheers
