I am doing this conversion now on my 1980 Spitfire. I had to transfer and drill 2 holes in bell housing, cut the snout off the transmission input shaft. The pilot bearing needs to be replaced and the clutch plate has a different input shaft with a larger spline. I am about to mate to the engine as soon as new motor mounts and slave rebuild kit arrives. I’m just changing the front seal on the slave fo to the after market one has a larger front seal that does not pass through the mount. I have not yet tried to install for the frame modifications.
