Sierra rear wheel bearing housings, how easy to make?

[Bonzo]

I have been looking at this particular problem for a while.

The Sierra hub assembly could be replicated to take a different size bearing. it is quite a simple hub.

The cost is likely to be prohibitive, as you say they would most likely need to be machined from billet with the added expense of having the bearing housings machined once the hub is made.

You may remember me posting a while back about plans for a rear/mid engined 7'ish car.

Some of the early drawings are taking shape. We have done some R&D on the rear hubs. Looking at the driveshaft issue, personally I think the most cost effective solution would be a hybrid driveshaft.

Donor engines CV joint on one end & donors hub joint on the other end.
