Pity my clients are all 2002 at latest

Why?

You can *create* the procedure within MS Access using the PROCEDURE
syntax e.g. I just tested your example

PROCEDURE MyProc [argSiteID] INTEGER;
SELECT * FROM Sites WHERE Sites=argSiteID

in Access95 and it works fine and will work for all subsequent
versions of MS Access.

You can *call* the procedure within MS Query using ODBC's call syntax.
Again, tested fine in Excel95 and above.
