Xack: You'll definitely need a model to create a pattern
Agree. We do not have F5 & WC Cobra's in South Africa, therefore I unfortunately have not had the opportunity to work on them. joey4420 has been very helpful in supplying measurements for the Gas Filler. Next week I will be doing a fitting on a Backdraft Cobra and I will make a cardboard model of the Gas Cap, with it placed in the correct position, I will work on a new pattern for the WCC which should also fit the F5
Xack: I would not want to be the guinea pig

. Looks like joey4420 might volunteer for this. Not to worry joey, I'm the
BEST on Planet Earth at making Cobra Soft Tops
