[Gmecm] More L31 questions- crank and cam position sensor.

Crank sensor is in the timing cover, which is ~$25 new from your local 
dealer. Behind the timing cover, on the crank shaft is a sensor wheel. I 
haven't priced this from GM, but I would think it's available. Cam sensor is 
in the distributor.

A good option to get all this might be to find a blown engine at a salvage 
yard.
