Very hard. Not impossible, but you had better be very good at fabrication. Plan to basically cut up the rear half of the car to do it. The existing mounts and various parts will need to be cut out to make room. Then you will need to cut and build new frame perches to take the sub frame front mounts and build a cross member over the differential to accept the diff mount. Then it would require cutting and building shock towers to accept the FC shock/spring.

Needless to say it will also need to be properly aligned side to side, up and down, and in line with the chassis. There would probably also be a lot of clearancing of the floor pan for room to fit the bits and pieces as they move through their arcs. The track width of the FC rear is quite a bit wider than the FB so you will have to run flares or a wide body to keep the tires covered.

I looked at doing that at one time, but decided it wasn't worth it for a semi-trailing setup. It would make more sense to build a double A arm setup or adapt in an FD setup for the amount of work that would be involved. Personally I wouldn't recommend it, but you can try it if you want.

Someday we'll actually get a report on using a screw type supercharger from Duffman692002 when he gets the darned thing on his. I'm not holding my breath on that one though.
