Its a c4 corvette pump, that's the application. It turns counter clockwise. Its not a short pump, its not a long pump, its not a standard serp pump found on trucks. Order one for a 84-91 corvette.

I agree with ex-x-fire - if purchasing a pump, just buy one for a 84-91 corvette. this is something you need not worry about. BTW, I recommend one from flowkooler --

In March of this year I put a new Autozone WP on and paid $42. After 10k miles still working fine.
