Thanks Stomper. Shoot! (Striking my palm against my forehead!) I still have a Sig mount in my workshop (somewhere)! I haven't looked at the aluminum mount or firewall very closely yet. Did you have to reposition the blind nuts to accommodate the Sig mount?

Yeah but no big deal there. Just measure between the existing blind nuts( horizontally ) both top and bottom to find center. Now draw a line between them and you should have a vertical line on the fire wall. now do the same thing top to bottom to get your horizontal center line.
Put a screw in the blind nuts and tap them out. I took some wood dowel and filled the old holes glued in placed.
Now clamp the engine on to both engine mounts ( if you are using a tee mount )and rest the back of the mount on a table and measure the space between the mounts. take that measurement and split in half. With the split number measure from your center line on your fire ( rember your center line will be off set, not dead center of fire wall ) wall and make a mark both top and bottom. This is where the mount will sit. Now align the center marks found on the sides of the mount with the center ( horizontal ) marks you made on the fire wall. Drill your new holes for the blind nuts and your good to go!
