[Shotimes] Misc related to subframe bushings

[James White]

I was also worried about corrosion, that is why I got the Delrin ones from
Courtney for the '95MTX.  And like the AL, they also need to be retorqued
from time to time.

But I am now worried about the standard ones on the '93MTX.  Never has had
the recall done, but Doug did the clutch on it 3 years ago and said that the
subframe bolts looked OK then.  I also noted that he modified a torch so
that it would fit through the subframe so he could heat the captive nut.

'93  5 SPEED   278k few mods
'95  5 SPEED   247k lots of mods (waiting for new cats..)
"double clutch"  it's good for both you and your SHO
