i ordered lower hose for a 70b or 71 b/e from year one for my 70 e-body with bb and 26",and it fits like a glove with penta star and pn.maybe not the right pn for 70 though,dont know.the hose is VERY thin,maybe they where thin originaly from the factory in 70,dont know that either.im never ever going to buy corbin clamps again from year one,as they dont seem to care what size clamps you order,i guess a blindfolded ch....e guy packs them. ah,now it feels a bit better.well i got me the right clamps from tom rt and mounted them on the hose and me and my hose lived happy ever after.do you live in usa,try frank badalson,i bet he has hoses and can manage to send within the us of a.
