Received the hoses yesterday and the Continental 60291 is a not a good fit. It has an angle that looks to fit a thermostat housing that comes off at an angle vice vertical like a Mopar. GM fit. The lower looks like a good match but won't know until I finish up some motor work. Neither had internal spring, the wall thickness of the hose is very good, especially the lower.

The parts had the Conti web site, when I went to their website the 60291 is not listed for a 70 road runner. It you type the 60291 it comes up primarily for GM vehicles, but then does show Mopar 70-74 B body and vans. Not sure why that is there as it will definitely kink the hose trying to fit the vertical thermostat housing.

Typing the mopar part number has no cross for the upper. Typing mopar lower and the 60659 comes up.

So it does look like cut to fit, or reproduction are the only options on a 22". Will look into that A body one.
