[s-cars] BTDTs for the tranny and engine mount pull and swap?

[Mike Fitton]

I did these a few months ago, along with an 034 snub mount and bracket.

Transmission mounts were cake.  I recommend filling them up with window
weld or casting urethane for a more solid setup.  Left engine mount was
also cake.  Right engine mount was difficult, but if you're removing the
exhaust I imagine it'll get a lot easier.

I'm thrilled with the package of five mounts, but I wanted as stiff and
long-lasting as possible.  I considered the delrin engine mounts, but
I'm anti-delrin for a couple of reasons.  It certainly would have been
stiffer, but I think it transmits too much vibration and I don't think
they last forever.  In the urQ world, some people used it for the
control arms and it caused stress cracks in the subframe.  The poly snub
and the urethaned transmission mounts probably contributed the most, but
all of my old mounts were shot, so the difference for me was pretty
enormous.

For the snubber, I chose the low-shore mount.  It's still like 800 times
more useful than the stocker, but I like to think it transmits a bit
less into the cabin.  Vibration is there, but I stopped noticing it
after a couple of days.  It's just attached now.  I got the old style
snub bracket which had to be slightly modified.  I think they redesigned
that bracket since then so I'm guessing the new style doesn't need any
drilling.

-Cheers!
