I just raised the rear of the motor from the bottom of the bellhousing. My tranny mount was in place for installation and removal. You can probably get by without touching the motor mount fasteners unless you have steel motor mounts as the original style mount will flex. Loosen the fasteners if it makes you feel better. Just note where your mounts are to the frame at motor and tranny mounts with tape should the unit move you can get it back the way it was. Of course if your sidepipes are uneven from side to side or within the hole you can tweak with shims, etc. to do the alignment job. Your wiring, plumbing should be okay. Sidepipes are questionable. You're not lifting very much just enough to get the tranny studs out of the crossmember holes. A couple of the fasteners to the sidepipe to headers are a beach so I'd be tempted to try before taking them apart. The tubes will flex so again you may be okay. Just watch it closely and you make that call as I haven't done so myself. However, I can tell you will not permanently bend the pipes. Good luck!
