[s-cars] Transmission Vibratons? (long)

[Eric Renneisen]

OK, after a couple of your suggestions, I decided to take a close look
at the subframe bushings.  For some reason, I was thinking the tranny
mounts tied directly into the body rather than the subframe, even though
I've changed them several times and looked at them every time I searched
for the source of the vibes.  In my mind, the subframe was out of the
picture when I had the halfshafts out, but that's clearly not the case.

So I pulled the rear 'frame mounts.  They seem pretty solid, but upon
closer inspection, they've started to separate:

Does that look bad enough to cause my problem?  I'm definitely replacing
them either way.  AutohausAZ has Meyle/Corteco for $21 ea, or should I
spring for the dealer parts, or is there a better option (for a street
car--no poly/delrin/alum, thanks).

Thanks for all the suggestions so far,
Eric R.
