rear 1/2 of twin - shock tower tech - inputs welcome

[amalventano1@comcast.net (Allyn)]

ok, so i've been thinking of what to do in the rear of the twin. ref this
page:
http://www.intenzmedia.com/fahlgren/cars/vw/stuff/rear_engine_scirocco/
first, keep in mind thats a mk1 (not too much difference).
scroll to the last couple of pics and check out these thoughts:
initial background - intend on fitting complete front 16v suspension +
engine in the rear.
- i plan to use coilovers (possibly ground control), and therefore it may be
possible to keep the stock body as far as strut towers go (if the shoe
fits...). keep in mind i would reinforce the towers, so there would be no
problem there. difference in tower height (vs. front towers), should be
close enough such that the adjustment on the ground control system could
correct for it (or i could just modify the perches). For the techies, the
rear kingpin/caster angle is almost the same using the stock tower points in
the rear as compared to the same suspension as it would be in the front
(just fyi).
- problem: i need bearings vs. bushings (like in the pic). I'd like to keep
the stock mounting point as far as the strut towers go (so that i dont have
to cut/weld the mount points). the reason i stress bearings at all is that
im not sure if standard type rear inserts will do the job (from a
maintaining alignment perspective, as rear alignment will no longer be
determined by the tortion beam). the slightest shift (even in poly) may have
large effects in alignment.
- question: so are there any upper strut bearings that anyone can think of
that may be adaptable to the stock rear tower mount points? the ones in that
last picture look close, but they also look like they rely on the shape of
the tower to fit properly (meaning i would have to cut those 2 sections off
of a car and cut/weld on the rear of the twin).
- basically im trying to maintain as much stock structural integrity in the
rear tower area.

thanks in advance for any inputs/time spent
