I really appreciate your willingness to help me out here!
Unfortunately, I purchased the Borgeson pump, steering box, and hose kit from Summit Racing. It was their mistake as I ordered the correct one for a 383BB.
I finally got a hold of them today after an hour of listening to elevator music recorded voice messages, and I was promised to get a call back tomorrow morning. She said she was going to call Borgeson and see what they said. (I told her what you said)
I live in Canada so I want to ensure that shipping will not be an issue for an exchange item. I do not feel it should be my responsibility...I paid the first time lol
