Correct heater hoses?

[firstgenaddict]

What are the correct heater hoses for an early 69? " 4th week October TT and a first week Nov VIN...
I have seen the heater hoses with the grooves and the ones with the GM and the square on them...

69 and later Hoses are Ribbed - with no markings.

68 and earlier had the larger hose marked with the GM logos

I have seen them both ways... on Survivors...
Ex. The Silver 69 L78 Survivor at the Camaro nats last year had GM logo hoses.

From what i have seen - only some of the very early 69's got the GM logos.
It seems they likely used up the remaining stock before switching over to ribbed completly.

Really for the most part - "GM logo" heater hoses disappeared in very early 69.

Correction  --  After reading your TT dates more carefully - yes you could use GM logos for the Oct car.
