the 5/8 stand-off goes to the rear......That's why you have so much space between the rear deck and the stand-off

The front stand-offs are shorter to save weight. I made the rears higher to eliminate the play versus the shorter stand-offs.

Did you use the 2 spacers per motor pod screw? Looks a liitle high in the rear, unless that's the photo angle playing opticals on me.

Otherwise it is sssssssswwwwweeeeeeetttttttt, of course I'm biased.
