A question for the serious ITR guru's...

Recently, I had a 97' ITR motor dropped into my Civic (i know.. shoulda done it myself. 2 babies and a recent move made it tough). Since it's an autox project, I'm running PS, and I've got a GSR rack in the car right now.

Went to the junkyard where they have a wrecked ITR (may be a 99 i think) and bought all the PS hoses off it. When I got home, I discovered that the end of the PS hose that actually bolts to the compressor is a different size. The 2 bolts on either side of the opening line up, but the hose-end is too large to fit into the compressor.

So, here's my question. Did the ITR PS pumps change, or did the guy who did my swap not give me the pump that came with my motor? (possible, but not malicious) My plan is to go try and swap out PS pumps at the junkyard I bought the rest of the stuff from, but I'm curious to know the answer to this. Thanks!
