I recall a poster claiming the belt from a *very* early 260E (86?) would fit a later A.I.R. pimp-equipped M103 when the A.I.R. pump had been removed. I filed that in the 'mental bank' in case my A.I.R. pump went out ...

Let us know what you do - the A.I.R. pump replacement would probably exceed the value of our car ....
