Which end to cut ugh!!

Tip #1: unless his user name is Rusty Rat Rod, don't listen to the guy at the parts store.
Tip #2: if you have an aftermarket anything, even if it's an OEM replacement, don't expect it to fit right up. Aluminum radiators are near the top of this list.
Tip #3: take the hose you have, and get lost. Lost in the parts shelves at the auto parts store, that is. You know what you need, you now have a handy reference, you'd be surprised how close you can get from there.
Finally, Got it. I had to trim almost 3" off the top end. Also it was a big help to have somebody up top while I was down below. But I finally got the hose to fit. It is a little restricted at a bend, but I think it will soften up with time. Temp is running where it is suppose to be. What a pain in the ars
