Andy your motor plate and alternator mount setup has been on my with list for a long time. Needs to be done as I run a 16v system and charge between rounds. Several times this year they called us up before I was charged. It makes it hard on the system especially running fans and water pump between rounds in hot TX weather.
I am also looking at pulleys for my ATI 917122E Super Damper and 16v alternators that will work with your brackets.
Guess I need to sit down and put together a list of parts because it is one of the upgrades I plan on doing over the winter. This thread reminded me to add it to my list of To-Do stuff LOL.
