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.

1967-1972 Corvette Wittek GN48 Hose Clamp Replacement for GM 9423581

Price: $0.02
Out of stock
Item Number: 4166946
1967-1972 Corvette Replacement Wittek Hose Clamp Replaces GM 9423581. Use 1-2 on air cleaner crankcase vent hoses. Good enough for a driver, but will not pass for original.


CAVEAT EMPTOR: Learn how to ID the Wittek original clamp versus the oversize replacement. The taste of a sweet deal on a repro is poisoned when you realize the following.

Above Top original Wittek GN series # 48 with 7/16" wide band. Bottom repro with 1/2" band

Above: Left original Wittek GN series # 48 with narrow saddle. Right repro with wide saddle

Above Left original Wittek GN series # 48 with narrow #4 saddle. Right #20 oversize saddle

Above Left original Wittek GN. Right repro with oversize saddle

All of the various size reproduction Wittek clamps use the same size saddle, however originally there were progressively larger saddles for larger clamps and smaller saddles for smaller clamps. This saddle determines the roundness of the clamp. Using these large saddles on smaller clamps causes to clamp to tighten into an oval instead of circle. Hence they leak slightly and never can be tightened
WARNING: Commonly termed Tower Clamps, the tower does not form until the screw is tightened. Caution: use pliers to hold the captured nut at the base of the screw while tightening the screw. We recommend they should be tightened slowly in this manner. Never use an air powered wrench. No warranty for fractured clamps. 
WITTEK SERIES: This OEM had many product lines including: Straptite, Suretite, Auto, SG, GM and GN series. These referred to a different style of clamp, not a clamp used on Auto's, nor did the GM refer to General Motors. GM series clamps used a 1/2" wide band. GN series clamps used a 7/16" wide band. SG were stainless miniature clamps. 
Yadda, Yadda, Yadda I was an authorized distributor for 20+ years until they went belly up.
