I looked at post #17 you referenced, and I suppose I could make eithier the 2 1/4" size stretch, or clamp the 2 1/2" size down to fit my 2 3/8" OD rails. the 2 1/4" size is priced at $5.66 apiece, and more for the 2 1/2" size. So I think I’ll check into the radiator hose. Thanks a bunch @Wayne for the offer. I apprieciate it greatly!
@don_mannes Do you like how your radiator hose is working? do you see any reason why not to use it? Also, assuming that a 2 3/8" size is not made, what size do you think would eithier stretch or shrink to fit? (I’m not real familiar with radiator hose and its properties)
