Ford 10 hole wheels

Does anyone know if these were ever produced in at kit? I would like to get my hands on some so I can complete my Mustang LX trans-kits

I don't think they were ever in a kit...
maybe a T-bird...
R & M had them in resin and I thought i saw some on best resin.

I'd like to find some as well. The only 10 hole wheels I've ever seen in a kit were 1/35 scale, which really doesn't help matters.
