Does anyone have a lead on where to find a 1966 "B" Body big block/Hemi Molded Radiator Hose 2658810 for a 26 inch side outlet radiator. An aftermarket would also be acceptable.

I am not having much luck in finding the correct hose and I do not want to use a universal flexible hose.

Thanks for your help in advance.

Have you checked with GATES? They carry the hose for a '64 Max Wedge so I would hope they would have yours.. You might be able to stencil a date code and part number on it if it really matters.

Gates p/n... GAT20355

Thanks Fred. That did the trick.

I have an early 67 Hemi car that origionally came with the 66 & earlier thermostat housing and I changed it to the aluminum 67 style to avoid all the comments at the car show by the supposed experts. I am going to change it back to the old style that came on it.

Just found this thread.

Anyone find a ready to go on upper hose for a 1966 Hemi car

Im thinking stamp my own if not

Gates says the 20355 doesn’t fit that application

Found the Gates on-line catalog and it was interesting. If I specified a 1965 Belvedere with a 383 I got the 20355 and the photo looks like the right hose for the early thermostat outlet. If I specified a 1966 Belvedere with a 383 I got a 20875 which looks like it is for the later thermostat outlet.

Same here, I don’t have one to go buy so not sure how it looks. I’ll look at the radiator today.

I found an AC delco number 20013S that looks just like the gates 20355 hose.

And from an initial test fit it sure looks like the nos one I posted earlier

Im waiting on a new thermostat to arrive ,,,,But can have pictures later this week on it all installed . And I'm using the earlier thermostat hsg as well
