Start to finish was about 2 hours. We'll see how it works. I MIGHT install this today, weather permitting. My garage is still occupied by a Jeep.
It will have limited vibration damping if my other idea works out. Need to get to work and use a laser for something.......

I wouldn't suggest this until AFTER you rebuild the trans. Remember the 00 and newer don't have torque axis mounts. Even with the hockey pucks, their motors still flex more than this one will.
The bad part is that replacing the oddly shapped rubber wedge isn't really an easy proposition.
Since my diff and trans passed their stress-test, I'm willing to give this a test. But keep in mind the final version may look totally different, too.

This is boosty thread on how he did his. http://www.bonnevilleclub.com/forum/...ic.php?t=71445
Bill asked me to post this to ask why you didn't try something like that.
Bill and i are going to check his rubber and see how its holding up to 15K miles.

I didn't try something like that because it still allows flex on the 'main' side of the mount. He felt a difference I'm sure, but the mount will still flex under torque load. The shock changes were the only thing he did, and it'* too far off the load axis of the mount to make a big enough difference.
I ripped apart a new OEM mount in under 1000 miles.
Think of it this way:
The big rubber wedge takes up probably over 75% of the load (remember that 92/93 Bonnevilles don't even have the shock). The shock only dampens the initial load. But because of how far off the load axis it is, stiffening it up will only improve the strength of the mount by 25% or so. These numbers are rough guesses, and could be confirmed with CAD modelling and stress analysis.
Improving the wedge problem targets the main failure.
Boosty made the change primarily for a header fit issue. His solution worked well for his intended purpose.

Test results favorable. Alignment was a tad off, but it worked. Final 'street' version is welded from my 1000-mile failed non-shock unit. Drying it off for paint right now. Have a burned hole in my shirt, and I smell burnt rubber, but that'* ok.
Not sure when the install will happen. I still have a Jeep in my garage, a toyota pickup in the driveway (for repair also) and I'm not feeling like getting rained on in the dark.

So how will this affect launches? Any fear that tire-spin will be harder to avoid, due to the lessened flex there?
As you said, the dif is a weak point, but assuming that you don't have a dif failure, the tires are the other weak point.

I have slicks.
This mod by itself may be the difference for me between 1.9 second and 1.8 second sixty foot times. I ran Woodburn this year with a 'under 1000 miles' failed mount. And still pulled 1.9 sixties.
There will be a couple other nice mods coming by spring to back all this up too.
Today'* pics:
Judging by the misaligned test unit, it'* best to start with a non-shock OEM NEW 92/93 mount, and reinforce it.
I'll have pics of the other 'goodies' to reduce vibration later.

The only problem I encounterd on my solid front mount was, the back corner of the mount, were it ALMOST touches the transmission becomes an interference fit with the newly welded steel in place, I need to make a few modifications to mine to make it fit properly, I cut my shock out of place as well...its been sitting in my desk at work for over a month now, I did leave the rubber piece in as well..mainly cause that bitch wasnt coming out without a fight lol
