Thank you for taking all the time to write and research all of this. I am a bit delinquent in my reply, as I have been a bit busy. Scott (builder) doesn't care if I source the parts, they just need to be right. My block is still in line so it will be a bit before it gets any major work. This was part of the deal when I brought it to him. I'm in no hurry, as long as I have it by spring.
I checked out a bunch of the butler stuff, and it looks pretty good. I'll post what I end up buying.
Again.. Thanks to all who took the time to reply, it is really appreciated.
