you can also convert the old oil pump to mount the CKP, I have converted many non obd swaps to obd2...its not a problem, you will need the ckp sensor and a crank gear from an obd2 bseries, with those I can tell you how to mount it so it reads correctly, otherwise you have to buy an obd2 oil pump or go obd1...pm me for more details its kind of complex to explain in writing but I can show you in a second or two...
