Fellow enthusiasts,

I am continuing to search for the source of my tub tilt.  Several people
have offered suggestions (thanks!) and Gary says he has the same problem
but on the passenger side....

Question:  Where can I support the suspension at each wheel (without the
tires in place) so that I can measure the geometry of the suspension
components?  I'm a little reluctant to just put a concrete block under the
lower wishbones and trailing arms.

Status of tub-tilt:
 Additional measurements chasing my tub-tilt problem (warning: the
following table may not be readable with proportional fonts):

Measurement (inches above floor)       Pass.      Driver    Pass-Driver

Rear suspension:
Bottom of frame at attachment of       6 3/8       5 5/8      + 3/4
outer trail arm

Front suspension:
Center of trunnion pivot bolt          8 3/16      8 3/8      - 3/16

Bottom of frame at front               5 5/16      5 1/8      + 3/16
suspension tower (between welds)

Center of upper fulcrum pivot         19 5/8      19 1/2      + 1/8

Comments and Questions:
- The tilt is much greater at the rear (I have new springs and poly
bushings, however)
- Oddly the trunnion pivot is higher on the driver's side. I'll check the
tire pressure
- I may swap the springs on the left and right sides (but what a pain...)
- Can anyone confirm which, if either, side is the correct height?

TIA,
