1966 Indy wheels for Firestone tires

[expatriate00]

Ok, I’m trying to reinvent the wheel, literally here. I’m modeling the 1966 Lola T-90/92 and I know they wore the standard Firestone tires. I’m trying to be mindful and aware of aftermarket offerings but so far have only found similar offerings, not an exact match. scale-stars.com/product/18-work-meister-l1-3p-styles-1-24/. These rims are 18” in 1:1 scale and have no slots in the spokes. But I don’t know if they’re even the right size. So,
1. What size rim were the Firestones fitted on? 
2. Does someone make a 6 spoke slotted Lola rim in the correct size? (One that doesn’t require spending $50+ for a vintage kit that will be wasted to sacrifice for rims.)

TIA

As far as I know there is no aftermarket match for the 6 spoke Lola rim

I am currently doing a full 3D kit of the Lola T-90 and will be doing the wheels shortly if you have access to a 3D printer I would gladly send you the rim file when it's done

MikeB,
I’d gladly accept any help you could muster with 3D printing. I have a Phrozen 4K mini for the job. Let me know when you make some progress. I had a line on a Juanjo Lola T-90  kit, but that fell through. 
Thanks
