How does a mammal remove the rear bolt from the rear trans mount
in an '89 civic. The firewall pretty much covers the bolt. I can't get
anything in from any direction. I'm rapidly losing what little is left
of my sanity.

 

Use an extension, swivel it way in there and turn it from underneath, so you have to do it under the car. Kinda difficult to describe but if you have air tool, it'll be much easier

 

Maybe they changed this in the '91, but in the '89 there's only about
18mm between the firewall and the subframe and that clearance is
at about 40 degrees from the plane of the mount. Can't drive a socket
from the bottom. Thanks for your response tho.
