Cairo, thanks for the detailed description of the procedure.

Couple of questions:
- who's the manuf. of the mounts?
-did you pre-tension the rubber buffers to "dist. a" as per manual

- if you did so, how is the feeling ?Did you use any kind of threadlocker on the lower screw?

I personally would not be worried too much about the lack of the heat/fluid shield (would just use a DIY shield out of a tire tube and a cable tie...not a beauty contest there).
