Is the back cap from an imco sc drive interchangeable with an older bravo XR?

Yep it should be. I have an IMCO rear cap with the steering ram mounts on an "older" xr case (circa 2006). They're compatible with the newer swept back XRs too, they just look a little funny.

Yes they will fit, but you need to drill and tap two more holes. There is also two different widths on the steering ram holes and one is a blank that you can drill yourself. I have a new blank one if you are interested.
