motor mount part #3950113
 

This is in reguards to my 69 Nova for sale in the "For Sale" section!Just out of curiosity i noticed the drivers side motor mount "frame side" had part number 3950113 on it! Just wondered if anyone knew what that was originally from!I think we have all come to the conclusion there were no BB's made with air but I just wondered what the motor mount number originated form, Thanks Duane
