[Supras] Pre-89 subframes vs. 89+ subframes

[mike at milisake.com]

While I prepare to install the Lexus engine into my '87 Supra
(http://1uzsupra.com) I am gathering all of the measurements to make a
decent set of engine mounts.  Recently, I measured approximately 18 5/8"
between each mount structure on the sub-frame (bottom of slot to bottom
of slot).  I also measured the angle of each structure to be
approximately 48 degrees on the passenger side and 50 degrees on the
driver side, however these angles are more likely due to the way the car
is sitting without the engine and various other pieces in it as well as
how level the garage floor is (although the Lexus engine mount areas on
the block measure almost exactly 45 degrees).

My question is for those with both types of sub-frames.  What
measurements do you have from bottom of the mounting slot to bottom of
the mounting slot on the sub-frame (btw, the mounting slots are
approximately a 1/2" diameter on my sub-frame) and what are the angles
on the mounting structures when you measure them?

Thanks,
Mike
