uh....
you put the d-series mount on the b-series block....
ive got mine sittin out in the garage, with the d-series mount holding the motor in, and it works fine....
you take off the gsr mount, and the 2 mounts on the d-series mount line up with the 2 further-left holes on the b-series block....
you bolt it in, and mount the motor in the car....
whats so hard about that?
