Canvas top Snap Size?

[murfulater]

I'm getting ready to purchase a Hoover Snap tool to replace some of the worn out snaps that won't hold anymore and wanted to know that size snaps to purchase (3/8" or 5/8")? Also I need to replace a few of the Studs what length of those should I get? I have a 2100 SR2

Should be the 3/8's.

If unsure to buy some at a local store to test.
