'64 non AC heater hose retainers

[Garry B.]

What is the consensus on what retaining device to use on the heater hoses for a '64 non/AC 327/300, aluminum straps or black clamps? I have one vote so far for the aluminum straps, but different vendors of these two items seem to have differing opinions. The car will never be judged, but I always like to be reasonably accurate regardless. Thanks.

I believe the strap didn't change until 65 model run, AIM for 65 lists on 3-19-65 clamp 3136266 changed to 3770259.

If These are the straps you are talking about, I haven't seen them on a 64.

Check Noland pgs. 224, 225 and 229 photos (of early 64 cars).

The Road & Track picture of Dec 64 shows a 65 FI with what appears to be the solid metal retainer, while Nolands book
has many examples of the 64 still using the strap so perhaps the change over was during 65MY.
ps have found other dates in Noland and the AIM a little off, well it's a corvette!

Alan, late. Mid June of '64. VIN 195XX, so a couple of thousand before the last one.

Don, I know your vote is for the aluminum straps. Any chance they switched late in the production? Your evidence is compelling at least for early VIN cars.

Harry, it's nice to know what NOT to use. Can you share with me what IS correct?

Garry, I'll be looking at 64 # 7XX tomorrow. I'll post tomorrow what I see, well maybe Sunday.

Re: '64 non AC heater hose retainers

All photos in Noland's book of 64s show factory pictures of the aluminum straps, the 63 and 64 AIM show same strap, 65 is next type solid steel. Must have changed very late in 64 for 65 run. Check Motor Trends Sept 64 issue with road test of 64 FI Corvette, still shows the aluminum straps on heater hoses.

I have an early June '64, 192XX, and it has the aluminum straps, judged good at last year's regional.

Re: '64 non AC heater hose retainers

Thanks Harry, although I think it's pretty clear that the earlier VIN's had the straps. What is not clear (yet) is when did they convert over to the clasp. Late '64 or did they wait until model year '65 started? Anyone out there have a later VIN than 19500 with original straps or clasps? Thanks every one.
