I'm leaning towards some pattern of grooved hose for both sizes as opposed to "GM" ink stamped with squares on one and grooves on the other.
Anybody have or seen a low mileage Canadian survivor?
1966 Strato Chief 2 door, 427 4 speed, 45,000 original miles
I couldn't say that it is but it's very useful to document nonetheless
If somebody has a 64 matching the 66 hoses it could then be determined by bookending too
I always thought it was ribbed, non-logo hose for the heater, but then I saw a Motor Trend article on the new 1967 Firebird & it had stamped GM heater hose (which I thought was at the dealer by the roll). Maybe a pre-production press car?
