Wittek Heater Hose Clamps 1-1/8 or just one inch?

[6s1640]

Hi all,

On the 65-66 Mustangs and GT350's, were all the heater hose clamps the  1-1/8 or where there some 1.0 mixed in?

Thanks

As I recall from previous discussions on the old forum, they were 1-1/8 but we discussed the difference of the two on the by-pass hose being narrower in width. They were marked with a "2" vs. the wider ones being marked "10". Correction:  Both were 1-1/16 but the by-pass is 7/16 wide. The heater hose clamps are 1/2 wide.
