There seems to be more than one size for the '75.

Here is what Willcox shows. I'm guessing you need the 6 5/8"

Send them an e-mail and see if they can tell you which one you need.

Why don't you just measure it? Is it missing?

The car has air so it will need the larger of the two pulleys. I made a note on the site for future reference. Here is the link:
