I am installing a cosmo 13bre and turbo II xsmn in my 72 RX2 and would like to find out if anyone has done this swap. I am currently running a 13bna supercharged with a 79 5pd. I will be swapping over my externals to the cosmo. Front cover problem with the mounts? I have the tail shaft(york), starter, cosmo counter weight,and shifter. I think all I'll have to make is a xsmn mount,locate shifter hole, and get my drive shaft matted and balanced to the turbo tail shaft. Questions or suggestions welcome.
