It is, whatever the carrier charges! Note that shipping 1 lb. to Canada with insurance is approximately $25-35. Shipping 1 lb. to Europe with insurance is approximately $30-40. Shipping 1 lb. to Oz with insurance is approximately $35-45. We DO NOT ship without insurance - because uninsured ones are "lost" or stolen by insiders.



We authorize credit cards with AVS (Address Verification Software).

AVS matches the credit card number with 5 Data Points.


 1.  Credit Card Number example: 1234 1234 1234 1234

 2.  Expiration Date Number example: 1219

 3.  3 Digit CVV Number example: 123

 4.  Street Address or PO Box Number example: 12 (# length can vary)

 5.  Zip Code Number 12345


If the network that authorized credit cards says all 5 numbers match – we ship. If the network that authorized credit cards says one does not match – we do not ship.


You may protest that all 5 do match – however the network may have wrong information. It matters not that the bill arrives at that address via the Post Office – the computer network often – I repeat often have wrong information.


After running credit cards for nearly 40 years – I will not argue with you. Only YOU can contact your credit card provider & make sure they are providing the correct information to the network used to authorize credit cards.


If however, your credit card checks at a DIFFERENT address – there is a $10.00 re-instatement fee.

1970-1982 Corvette Upper or Lower Radiator Hose Genuine Wittek 28H Clamp GM 2468878

Price: $0.00
Item Number: 4166900

Wittek 28H CLAMPS
According to Wiki GM produced 4,400,000 + cars  in 1970.
If each car used 4 of these clamps - more than 15,000,000 of these clamps were needed. Does anyone think that on only set of stamping dies produced all the identification markings on all of these clamps?

Does anyone think every one of them had the same exact stamping of 28H and Surtite or is it SURTITE or SureTite or Sure Tite or Surtite or SURTITE or SureTite or Sure Tite.

In my own collection there are 13 variation of the SURTITE and 28H stampings.

It is even a bigger stretch of my imagination to accept the ncrs proverb that most Corvette have only one font style, one point size & one location. Yea I'm not gullible. I doubt there is even one of those Black Hat Judges who ever worked with mass produced parts or even purchased a stamping die to produce a legend, part number or logo stamped into a part !!!!!!!!!
