An earlier 1500 (or even 1300 I believe) manifold will bolt right up to the engine but you have to replace the exhaust pipe as
well. The cat won't bolt to the older manifold as the bolt pattern is smaller. If you decide to go with another cat manifold make sure you have the brace on the pipe at the bellhousing. This helps support the extra weight of the cat and prevent the cracking (although no guarantees). Changing the manifold is fairly straightforward although tedious. The intake and exhaust manifolds come off together and you should replace the gasket. The bolts underneath the manifold are the worst as you can only turn them about a half of a flat at a time with an open end wrench. Do them first so at least you don't have the weight of the manifold making them even tougher to turn. When reassembling, be careful that the manifold clamps don't spin out of position as you tighten the bolts. Sorry I cant help with parts. Good luck!
