Need help finding parts for old Centurion "Elite" 10 speed

Hello all, I'm new to this forum and very happy to find it because I need help. I jumped into rebuilding my old Centurion "Elite" vintage 1978 or thereabouts and everything was proceeding uneventfully until I discovered pitted races on my rear hub cones and one pitted race on my bottom bracket axle. I went to my local bike shop expecting to find what I needed with no problem only to discover that these parts (at least according to the local shop mechanic) are hard to come by. Any help I can get in finding the following parts will be greatly appreciated.
Cones for front and rear hubs - The hubs are marked SunShine Pro-Am Japan 76
New bottom bracket axle - My bottom bracket threaded cup is marked Tange 1.37 x 24T Made in Japan. The axle measures 124.36 mm from the end of the taper to the opposite end. The diameter of the threaded part of the threaded cup is 34.5 mm.
If you know of a sealed bottom bracket that would fit my frame that would work also. The bottom bracket shell is 68 mm long. Thanks for your help

very nice hubs, but yes, you're going to be finding parts either second-hand or NOS. i found a set on ebay for about $20 in very good shape. i suspect they might be the same as suntour superbe hubs, but you'll pay a lot more for those.

either a shimano 68 X 122 or 127 BB may work. i tend to go on the short side when the original spindle fall between what is available in catridge units, but you should check to see how much space you have between the small chainring and the chainstay, and the max/min throw of the front derailleur. for that matter, check the original chainline as well; sometimes they're not so hot.
