Scott,

Here's the specs for the GMC reference:

Maintenance Manual: X-7525
Section: Front Suspension
Page: 3A-20

Front Ride Height: 13 1/8" +/- 1/4" measured at the top of the slot in the
frame 24 3/8" rearward from the center of the front axle.

Rear Ride Height: 11 11/16" +/- 1/4" measured at the top of the slot in the
frame 56 3/8" rearward from the center of the rear bogies / wheels.

Caster:
Check: +1 1/2° to +2 1/2°
Set: +2°

Camber LH:
Check: +1/2° to 1°
Set: + 3/4°

Camber RH:
Check: +1/4° to 3/4°
Set: +1/2°

Toe:
Check: 0 to -1/4" (toe out)
Set: -1/8" (toe out)

Your guess is as good as anybody's as to how to relate this information to
your Revcon.

I would suggest you Google front suspension alignment and maybe you can
figure out how to translate it into English from Greek! ;-)

Found some additional information for you to digest. From a service
technical bulletin from the factory. I give you the alignment specs.

Ride Height: 10" + 1/16"
Camber:
LH: +1/2* +1/4*
0*
RH: 0* + 0*
-1/4*

Left hand camber to be 1/2* more positive than right hand

Caster: Set caster at 0* + 1/2* on left and right hand sides

Toe: Set toe at 1/8" + 1/16" toe out.

Don't know if that helps. It's all kinda Greek to me.

Scott
