Radiator Hose Clamp Markings

[A26B]

We have had several requests over the last couple of years, for the original radiator hose clamps. Virtually all of my stock was acquired in boxes of take-off parts, so I don't know which year they might have come from.

Now, I have a customer needing the clamps for a specific year model, but I don't know which markings were on the different year models.

So, I need to access the knowledge of the Registry and build a database for the NCRS guys. If your ZR-1 still has the original spring style clamps on the radiator hoses, please look at as many of them as possible, 6 hoses/12 clamps, & poat the year model, which hose and the number or letter code stamped into the clamp.

example of data needed
1991, Radiator Outlet Hose, Stamped "V"
1991, Radiator Inlet Hose, Stamped ....
etc. Note, may be a letter or a number stamping.

Thanks for looking and posting. Here's an example clamp.

Well, at least it will be narrowed down to only 2 model years. I will take any data I can get and reduce it when possible. Thanks for looking.

Thanks for looking & the information when you can obtain it.

Wouldn't NCRS have this info? If they don't, then does it matter? I'll check mine this evening Jerry.

The ones I could see without mirrors or inspection camera's on my 90 were all stamped with an "S". The clamp on the bottom of the t tube had a small hole where the letter would have been stamped. Most of the clamps up high, in the line of sight were black, the out of site clamps were galvanized colored. -Steve

I am not familiar with NCRS. One of my customers wanted clamps specifically for the 1991 and I do not know what that might be. To him it matters, so I am just trying to accomodate. Thanks for looking.
