So I bought a 20621 but it wont clear the belt for the P/S on my 72. I ended up using the original factory 1 1/2" hose, I just used a couple of progressively larger impact sockets over a few days to 'stretch' the hose end to 1 3/4". Done
I believe I’m going to have this same issue this coming week with the radiator I ordered. Looking through rock auto, I think I found a hose that will work. 67 Galaxie with a 289 It shows 1 3/4” x 16”, which is the same length as the Maverick and the shape looks identical, as far as I can tell. I’ll post back, as to whether it works.
