[Harp-L] Changing Reed Plates (never done it)

[Phil Oetiker <poetiker@xxxxxxxxxxxxx>]

Hello!
	I've never changed the reed plates, just bought a new harp.  But, I 
have found a need for a High G harp.  Now can I put Lee Oskar High G 
reeds in a Lee Oskar regular G major diatonic?  Or can I put Suzuki 
High G replacement reed plates into my almost never needed Db 
Promaster?
	I'm guessing both answers are "yes."  But I wanted to check with the 
wise men of the mail list first.
	Also, do I really need a tool kit sold by the harmonica companies?
Thanks
