Hi Yes I believe so, unfortunately when I purchased the car for a total restoration the mounts had either been butchered or were non existent. the new mounts came from A Head for Healey's UK and were supposed to be the new uprated ones stronger.
I can weld up the holes on the pert that attaches to the rubber on the engine side and lower the holes so that will sort out the engine sitting a little to low, it only needs to be up by 3 or 4 mm. As for the holes which should correspond to holes in the chassis mount I can also weld up and change. I was just curious to know if I was the only person who has found this. On all of the suppliers site you can only fined two types of bottom brackets those for the BN1 & 2 and the ones for all of the BN4 to BJ7 cars.,
