M & A castings no longer make the wineglass style Halibrand. Image certainly do. There is no picture on their website, but they have the pattern and will make a set if asked (I just ordered a set....). Very accommodating guys.
Pat, your CAV wheels are six pin? In other words, just like original Halibrands.
I thought the CAVs like yours and mine all came with 5 pin wheels.....at least I believe that's what's on mine (haven't had the wheels off in a couple years...).
If you are looking for original 6 pin Knock Off wheels by Halibrand, I believe that I have a set of 5, back in late 60" early 70' My Mangusta was converted from a 4 lug pattern to a 6 pin drive and a set of Halibrand Wheels, I believe from a GT40 were installed and a spare. If this means anything the inside is also stamped Goodyear. They are in excellent shape. They actually still have original Goodyear tires on them. If you would like pictures I will be glad to forward them to you. [email protected]
Good luck
