The only option for aftermarket is OSCO. All others will interfere with the Selectrim trim ram/engine mounts.
I fixed up some cracked 3.8 manifolds years ago. Mine were mainly just pushed out on the lower rear curved parts, and then split near the drain fitting. I veed the cracks out with a die grinder, then drilled the ends of the cracks to relieve stress. Then I used a mix of JB Weld and fiberglass strands to fill. They worked great for 3 or 4 seasons. Then I found some NOS manifolds and foolishly tossed the repaired ones.
