[Replacement leather handle for '58 GA-5 Skylark]

Bill, thanks for the reply but I've found plenty of suitable leather replacement straps, I just need to determine the correct size for a late 50's GA-5.  If anyone can give me the approximate length or center to center pin on the strap retainers measurement it would be most appreciated!

[Replacement leather handle for '58 GA-5 Skylark]

I'm trying to source a replacement leather handle strap for a '58 GA-5 Skylark.  Three questions:

1.  What is the correct length for the leather strap?

2.  Are there any suitable straps available?

3.  Anybody know a source for the brass rivets that hold the strap hardware in place?  I managed to get some brass plated strap mounts.

Thanks!
