They tell me its for a '88 but this motor used a timing chain insted of a timing belt and the crankshaft at th trans end wont accept my old fly wheel.(trany bolts up perfect)...CAN I USE THI MOTOR ???

You should not use that engine because it does not sound like a compatible 1.6 liter engine, and it should be returned to the salvage yard and they should be made aware that the engine that they sold you is not compatible with your vehicle.
