I did this in mine before mine got folded up in the accident, and I don't remember anything special about the work - it was over 2 years ago. Some of my Venture posts I can hardly remember too, except that firewall vent nipple. Incredible detective work, and help... WON'T forget that!!!
I DO remember having so much stuff in place to MAKE SURE the engine didn't rotate back on my fingers while I was doing the work, that it was almost in the way. Didn't mind a bit tho', cause it was for safety.
I can't remember if I had something behind the engine too - 2x4 against the firewall???
