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.
