I'm using a HAPI VW mount for my 0-200 as did Marty Roberts. My mount has 1 inch aluminum spacers on the firewall. As I recall, the top mount bolts on the firewall are centered on the top spruce member on the firewall, in my case that is a 3/4 inch by 3 1/2 inch spruce plank, slightly bigger than the plans call for, and those bolts are in line with the top engine mount bolts. This puts the thrust line just a few inches below the top longerons and only a few inches below the horizontal stabilizer. I'm guessing that a few inches up or down from there will make very little difference in the handling, only the fitting of the cowl. As always, your results may vary. :-) Larry Flesner
