Spitfire/GT6 front hub drawings?

I may just make new hubs in a 4x108MM pattern for my "Trick-6" project which I am trying to get active on again.
Probably use 7075 aluminum since Ti would be too expensive.
My CNC lathe and mill have to be good for more than just the day job.

Seems like these have been in use long enough that drawings should be fairly readily available.
I will have to redraw them anyway in my CAD but still simpler than having to reverse engineer them.

Anyone have drawings or a link?

Yes I do know I could just buy them in the UK, at an exorbitant price, particularly after the exchange rate and shipping are added in.

My own time and tools are the "Locost" bit for me.

All you *have* to have is the outer wheel flange location; you can determine the various bores and the length of the hub from the bearings, grease seals, and dust caps.

The aluminum sprint car hubs generally have a fairly thick flange and a large radius on the back side.

Remember to cut away part of the center flange so you can drive the races out someday. I've encountered some cars where the center ridge between the races was taller than the races and ran the full circumference; the only way to get the bearing races out was to run a bead of weld around the inside of the race or cut the race with a Dremel tool.
