    Ron is correct...no ink stamps on heater hoses. i think that was a first gen thing that did not carry over to the 70 model year.

    With 1972 the Spoiler became optional.
    With D80 - high spoiler stripes
    Without D80 - flat deck lid with stripes
    Original paint 1972 Z28

    On many unrestored original cars there is single or double alpha/numeric code on the hoses - in one or TWO places along the hose... I have seen 3, DD, P, S, backward S and a B

    in 1974 the heater hoses had two letter stampings on them. Here is my 33K original 1974 z/28 with original hoses.

    So despite a new stable mate I got back to the Z as I want to driver her a bit. You may recall that as soon as I got her I innocently wandered into a trunk restoration, carb rebuild and then VA removal which was more then I anticipated but am happy with result. So what other obstacle to driving remain?

    I was annoyed that rear seam of headliner was split when car arrived. You can’t drive without the deteriorating foam flying all over interior of car. Besides being concerned with a new headliner in a 50 year old interior, i don’t want to get bogged down in headliner replacement so spent about three hours sewing it and a sun visor that had split on seam as well. Not fooling anybody and headliner still needs replacement but next sunny day I’m ready to roll.
