You need to be more specific about the part. The struts are different between the SA/FBs, not sure what mount you mean.

The 4 bolt upper mounts are the same. The two lower mounting points to the steering arm are the same.

Your brake lines have two different thread pitches. If you keep the SA calipers and lines you will be fine. If you use the FB calipers you will need to swap the hardlines or get brake lines that change pitch or an adapter.

The struts are also different diameters, so you can't use SA struts on an FB and vise-versa.

Actually, I forgot to mention.....You can use FB inserts in SA strut housings by using a spacer. Pretty simple as well.

Once the parts are off the car. Remove the nut that allows the insert to come out. Slide in a FB insert until it sits all the way down.

Screw on the insert retaining nut until it bottoms out and then back it off 1 or 2 turns.
Use a piece of tape on the shock shaft that shows where the top of the insert retaining nut sits. Pull up on the insert (Like you are trying to pull the insert out) until it stops. Measure the distance from the tape to the insert retaining nut. This is the thickness of the spacer you need to make.
