Hello Damon,

If you have your motor side tap for motor mounts, just use a standard engine
mounts that has a bottom rubber mounting plate and a engine side plate.
This is what I use. If you motor holes do not align up right, than use a
flat bar of steel with tap holes as a adapter.

Install the motor mounts, transmission, and dry fit the unit so that the
rear transmission mount is setting on the correct position on the
transmission rear cross member.

Make sure that the transmission yoke is not bottom out into the
transmission. Look up the specs to see what clearance you need. This
clearance is needed, as the rear axle goes up and down which reduces the
angle of the driven line, which allows it to slip in and out of the
transmission.

Make sure that the motor and transmission is level in relationship to the
differential, NOT INLINE, but is parallel. There should not be least a 2
degree angle in the drive line between the yoke of the transmission and the
yoke of the differential. If this is not maintain, you will take out the
needle bearings in the U-joints bearings, because they will not rotate
right.

After you have the motor and transmission correctly place, while hanging on
a engine hoist or some other lift, than you can reference a platform
position for mounting the motor mounts to.

I could use a little input on issues of mounting my motor. As soon as I get
my adaptor plate this will be the first thing I tackle. My plan is to
couple the motor and transmission together then mount the transmission back
in place and see how it all needs to sit before fabricating anything. I
have two potential mounting points, the original motor mounts, and a frame
member that looks like it will end up sitting under the motor in a very
convenient location. My motor has a flat metal mount welding on the bottom
plus several tapped holes in the case that we put there while we had it all
apart to be used during mounting.

So I won't have a lot of specifics until it is all hanging in place, but I
do have a couple of general questions. First, what considerations are
important when deciding how to mount the motor. I know that providing
resistance against the torque of the motor is a must, which is why we tapped
the holes in the motor case. Also, should everything be mounted with some
kind of hard rubber insulator to keep vibration from being transferred to
the frame? What kind of clever things have you tried that might work well
for me, and what kind of mistakes have been made that I should be sure to
