hotskillet,

yes, it's definitely improved the feel. i'm actually working my way
towards eliminating a noise that sounds like i'm riding around with a trunk full of loose tools -- er, well, actually i guess i was; but that's been narrowed down to some bad monroe shlocks
that the PO had on there. the biggest motivation for doing the
subframes was sloppy handling at the back particularly where there was a change in road grade, even as slight as hitting a manhole cover. sometimes it just felt like the front was going one way and the back wanted to go the other. that's now eliminated. the whole back end just feels tighter in handling.

the old diff mount was dry and cracking -- had definitely lost its tone.

there's a lot of dry rubber under there!
