As long as your taking things apart, inspect camshafts and the crank girddle on the block for scoring. You whole engine may be scrap, or everything could be perfectly fine.
If it happens to be just the crank thats messed up you can get a crank and a set of used bearings (i recommend new bearings) from any store that parts out SR's.
http://www.sr20store.com is one that comes to mind.
