A shout out and thanks to Basement Arcade for my kit! 1st thing I noticed when opening the box it arrived in was the engineering and quality that went in to producing this. This is a quality product.
One thing to note: on my ES, I had to mount the assembly not from the original mounting point, but about 3/4" back from the original mounting point, to create enough clearance for the institute to lower and raise.
One more ES that works the way the designers intended!
