S5 Engine bolt sizes

Hey all, I'm installing a new used engine in my 89 TII and I'm missing the 3 bolts that mount into the engine on the front motor mount. Mazda doesnt carry these anymore. Does anyone know the specs on these. Its 39-035A in the diagram below.

I think the bolts are M12 x 1.25mm x 30mm Grade 8.8 or higher. I'll give them a try and post back in case anyone else is curious.

those bolts are the same on every FC, so finding some should be really easy.

Thanks turbo_dave, Do you know the lengths on the bolts? I might try to get them locally cause my engine is still on the hoist. If not I will definitely take you up on your offer.
