I wouldn't sweat it until you get everything together. Try to drop it in, it may fit. Lots of people (including me) have done it without the drop center link. It's totally dependent on the car, mounts and oil pan. The 65 Valiant I put a 360 in didn't need one. It was close, but it never hit. Also, don't let someone bend you over on one, either. Firm Feel sells new ones.
