Front Wheel Hub and Wheel Studs

Hello:
Just purchased a 68 Plymouth Barracuda Convertible Survivor. I am going through the mechanicals' to make it a reliable driver. The front wheel hubs have LHT's on the passenger side and RHT's on the driver side. Several of the studs have been over torqued and the studs are not holding.
I would really appreciate suggestions on how the problem can be corrected. I would also be interested in purchasing nos or nosr front and rear wheel hubs.The hubs are malleable steel and the studs cannot be welded and expected to hold. I would like to keep the originality of the thread patterns on each side of the vehicle.
Go easy on me if I have not used the correct nomenclature.
Thanks
