I pulled my motor today, but managed to ruin the drivers side motor mount (Split Rubber) and also took a chunk out of the aluminum plate between the bellhousing and the block. I don't know the technical name for it but a small piece broke were the bolt goes, nearest the starter. Am I best off to get these parts strait from GM or does some one here have a better suggestion? Any opinions on welding the aluminum plate? Seems like theres enough room were I could gouge out the broken piece and weld it back together?
