Thanks.. I really did not want to order an engine and find out that didn't match. In my case, it will be hard to re-do the mounting setup, as the engine mounts on 2" bars of steel that suspend on rubber isolators along the frame. There is no flat sheet steel for me to pick and choose where I drill.
The reason I asked is because I found some documents regarding the mounting holes on various engines. I wanted to go with the Vanguard series with the HD filter and etc, but it lists as an "Odd bolt pattern, unlike any other engine" so I backed out on that option, fearing it would be more trouble than it's worth.
I hoped that all of the Kohler v-twins would be identical.
