Breather Hose - 273 HP CAP

Merry Christmas to all. Looking for an NOS or like new molded breather hose from the 273 HP air cleaner to left valve cover breather. This appears to be rather limited and was used on the CAP (Calif) motors. The parts manual shows it listed in section 14-29 as CAP, Air Cleaner Conn, part # 2465764. I'm assuming this is correct - it is the only reference I can find. The pictures will show the one I currently have. It looks good but is very spongy on the ends and hard throughout the rest of the hose. Any help with the part or recommendations would be appreciated. I have experimented with generic air, coolant and fuel hoses and nothing looks right because of the pre-molding on the original. Thanks for looking.
