87 Turbo II tranny, driveshaft, and rearend into 86 N/A Rx-7
 

I have a 87 Turbo II Parts car i just recently bought it has 111,xxx miles on it. I was thinking about puting the tranny, rear-end, and driveshaft into my 86 N/a and swapping a 13B-Re cosmo into the 86. How hard would it be to switch that over to the 86 , or does anyone have any advice i should take.

Thanks
