The easiest thing to do is remove all the Mazda mounts from the frame/crossmember and go to a salvage yard and get the correct frame mounts for that engine.

Then, put the mounts on the engine the way they would be mounted originally and set the motor in the truck, lift the rear of the engine to get it level and weld the lower mounts to the frame/crossmember.

That's what I had to do to get my 305 Chevy into my 1987 B2000.
