2009 387 Peterbilt Motor mounts / ISX 871

[Nostalgic]

There isn't much room in there to work at all... Probably the approach I would take is to remove the mounts from the rear structure. They're loctited in and tight, so some heat would be needed, provided you have enough room to get a ratchet on them... Doubtful without removing the transmission. Might as well call it a job, pull trans and reseal your rear structure and put a new clutch in it while you're at it.
