I too suspected the rear engine mounts, however I replaced them with the
new engine. I also got an opinion from another mechanic who indicated
that everything looked like it was in order. Also, because I had another
bad pipe and and a poorly cast collector knuckle ( all same aftermarket
brand) I had to return I suspected the pipe bend. Maybe the new engine
mounts are thicker, 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 ?
