Due to the timing marks being on the torque converter the bolt holes are not symmetric meaning one hole is offset. The converter will only go on one way it is best to mark one of the flywheel holes and the matching converter hole. If you didn't do that you have to install one bolt almost all the way in but still loose and turn the engine over to check the other three. If any of them don't line up take then out and move the converter one hole and start over. It is possible that you would need to do that 3 times before it matches up. At least a neon engine is easy to turn over by hand unlike a 440
