Motor Mount Compatability

I have searched and came to the conclusion that all b-series integra mounts are the same so long as the years are the same. So i bought some 92 GS 5spd. mounts and they won’t fit on my 92 GSR w/ B17 motor. Can anyone offer insight?

Which ones don’t fit?

Well the only one i have tried and needed to buy was the drivers side side mount and it is too thick to fit in the backet and too long…
