I have a 1960 Chevy Fleetside long bed that I’m trying to do a LS swap on. I am unable to find a transmission crossmember for a 4L60E installation. I have tried several classic part sites but have not had success in finding a comparable crossmember for this swap . Not sure why a 63-78 crossmember will not work but no one has recommended this. What can I use to help me with this?
