thanks guys.
totally unsure why he did that. he passed away and his kids are cleaning everything up so no indication on what his plan was or if he had purchased it that way himself. it was a package deal so not into it too deep. may just cut some plugs out and weld the holes shut. or throw it away. lol the water jacket hole is more of a mystery, it is tapped but if i am welding up holes anyways that should get a plug too.

i saw a few more things around his place that had the same kinda left field ideas. kinda sad that he collected so much stuff to just leave for his kids to throw away. they arent car people so i got there after the third dumpster had left.
