Need help on correct lower radiator hose on LS swap

[72farmer]

I just bought a 68 with LS swap. It did not have inner fenders when i got it. I am trying to put new ones on.
The bottom radiator hose is keeping the inner fender from going up to the bottom of the radiator support. It likes at least 1" and is hitting the hose. I am not sure what the radiator is out of. The bottom barb on the radiator is straight out and measures 1 3/4" in diameter. What molded hose (need part number) would give me the clearance that i need? Please help!!
