Crankshaft damage

[bruceanz@hotmail.com]

I had a knocking noise when i put my 1966 Mustang 289 V8 into drive (auto) at idle, we checked the crankshaft and it had excessive end play like 10mm.

So i pulled the sump off and removed the centre bearing cap to find that the transmission end of the thrust surface on the crank bearing was badly worn and it has worn into the crankshaft lobe. Has anyone had the same problem?

Plus can the crankshaft be welded and machined?
