B1 motor mounts

[pacetruckdrvr]

Can anyone tell me if the superjet mounts are the same as the B1 mounts? If not how can I identify the proper mounts for the B1? I have a box full of motor mounts I bought years ago, I just asumed they were all the same.
Thanks
Steve

b1 and fx1 mounts are the same, as they are flat. superjet mounts are angled.
