Hi Davis,
Well that is interesting about convertible/HT motor mounts. The mounts I have are identical to the one to the right in Fig 11 of the magazine article (in the mans left hand). Here is a pic of my pair in the same orientation. You can also see in this pic where some metal has been trimmed from the bracket near the upper bolt. The trimming has
not gotten close enough to any bolt hole so that the bolt head is completely engaged.
But after reading the article I can not tell if these are convertible or HT mounts!
