I think it would be possible to make it fit... would it be at all worth the trouble? NO. You would have to get the matching bracket for the pump, then shim it out to mount properly, and then it would work.
Where as, if you jsut need an accord PS pump, you can find them pretty cheap. I have 2 for sale right now, if your interested, pm me w/your zip and i can let you know what it'll be shipped.
