re this would account for the rear engine mount bar being closer I think ? They did look a lot beefier than the old ones they replaced ?" I did find this on a waterboxer engine recently. I was installing a new engine, and only the outer ones looked tired, of the four rubber rear mounts.. and I was going to just do those .. but they stood up noticeably higher than the other two older ones. so I had to do all four to keep things fitting right and even. So I could imagine you are 1/4 inch higher there.
