i have a crossmember that is still in my car..it came no motor or transmission..originally v-8 car..i see the crossmember has been notched..but i really dont know what its for..i'm thinking its for a 350..as this certainly wasnt a high dollar roller (lol)..i doubt it had a bbc in it...i just thought it would be nice to know before i dropped in the m/t...this crossmember looks factory with a notch in it.(78 malibu).thanks!!
