help with lower rad hose

[NicoSlam]

I installed a billet specialties serp system for my 69 with 350 and I'm having trouble finding a lower rad hose that will fit. I even purchased a SS flex hose but it rubs on the chassis. betweeen the fan shroud and lower then normal alterator, I have little space. I also thinking of the Napa 7371 hose which I'll try this week but I think I need help from someone who has used this serp system. I called BS but they could not support. here is a pic of my setup

I installed a Billet Specialties serp system and I am having trouble finding a lower rad hose that does not rub on the frame. I called BS and they couldn't help. I tried an SS flex hose but it rubs on the frame. Does anyone have hose suggestions or used this serp system?? thanks for all the help you guys can give. Here is a pic of my belt system.
