 This will allow you to directly bolt up of any of the Chevrolet style
automatics to your V6, the TH350, or the TH400, or any of the 700R4, the 4L60
and the 4L60E overdrives. With gas prices going ever higher, any and everything
you can do to increase mileage helps.

 Mine is identical to the one listed on E-bay and in excellent shape, but mine
also includes with it the later model engine side motor mount brackets that use
the less expensive and much easier to find Chevrolet interlocking style motor
mounts, which will prevent the engine from doing somersaults under the hood if
one should break.

 Just something to think about, but since converting to an automatic will
eliminate the 2 bell housing mounts and only adds one transmission mount, you're
going from a 4 point anchorage system to a 3 point, and the engine mounts are
the only thing keeping the engine upright under the hood. The original V6 motor
mounts are not up to task even if they are still in decent shape, once the
bonded rubber tears free from the metal on either side, the only thing keeping
the engine in place would be gravity. The interlocking Chevrolet motor mounts
would keep the engine in place even if the rubber did tear or break free from
the metal brackets. This would also prevent any kind of loss of throttle control
that could happen if the original style GMC motor mounts were used and failed.
Like I said, just something to think about.
