I've observed the frame bending syndrome on mine too!
I comiserated heavily with Matthew Pollard about this.
 We've collected photos from many TiiCo'ists and
strategised on various solutions.  I decided to throw
money at the problem rather than welding anything.

The alternative to welding the bracket to the frame
rail, or welding the pieces of the left engine carrier
together, is to replace teh left engine carrier with a
solid one.

You'll need two parts from an '83 diesel vanagon.  251
199 257 "retaining plate", and 251 199 203E "engine
carrier, left"; about $260 total.

Bolting these together is simple and relieves that
torsional stress from the pivot point in the old
mount.  It's been working great for the last few
months.  I've done some pretty nasty dirt-roads lately
too.

There is additional engine noise in the higher
frequency, but the motor really feels well held in
place now.  Used to be when I'd go through a pot hole
or over a huge bump, the engine/tranny would feel like
it kept moving a bit longer than the rest of the car.

Send me a note if you'd like some pictures or the ETKA
page describing the parts breakdown.

Happy motoring!
