Wanted: 1977 Corvette Original or NOS Heater Hoses

[72-SS-L48]

Hi Guys,

I'm looking for Original or NOS Heater Hoses for a base motor 1977 Corvette. If the hoses are used originals that is fine, however they must be in good enough shape to be put on a car.

Thanks,
Dave

Hello Dave,

I have some NOS GM heater hose that I believe was purchased back in the 70's or 80's for Corvette usage. Not sure if it's factory correct for your application because the books I have don't list these numbers.

Perhaps somebody on this site could provide you the info for these.... or...

Maybe you still have some original hoses to compare these to?

3/4" hose:
Group 8.962 Part #482420
Stamped "4230GM 3/4 INCH (19.0mm)"
Has a single rib/groove and another group of 3 ribs/grooves.

5/8" hose:
Group 8.846 Part #495692
No markings on the hose and no apparent ribs/grooves.

I have roughly 20 feet of each size and would sell it by the foot if it works for you. PM me if you have any questions or are interested...

Thanks, Charlie
