Installed the adapter today - it took a lot longer getting the old stuff out than it did putting the adapter in. It's important to have a filter on it before you lock it down in final position to make sure you have the clearances you need and that you can actually remove and replace it.
I ran out of time and didn't get time to fire it up to check for leaks. I expect that to happen tomorrow.
I can't seem to get photos to display in this post. Gallery is at
