Hello again Eric,
Thanks for the very helpful information, I have found the section in my
FSM too.
It really looks simple to make those measurements I must say.
The reason I asked around for some 1960 front bumper height measurements
is the fact that I don't have a lift available for my car. Ofcourse I can
put it on axle stands but if the measurements of other 1960 owners give
roughly the same figures I am worrying about nothing you see.
Btw, I have a preference for a tall sitting 1960 Imperial too, so I guess
it wouldn't hurt to check for cracked bushings.
Lost lower arm bushings will however certainly be noticable when driving
the car don't you think?
If one is cracked or heavily distorted, are they easy to change or do I
need a lot of special tools then? And even more important, are those
bushes still available?
Btw, I have Monroe Max AIR shocks in the rear and I am pretty happy about
it, I need them to compensate the weight of the LPG tanks. You can 'pump'
them up with an air compressor until the rear of your car is at the
correct level.
Thanks again for your help,
Robert

Subject: IML: Front End Height Without Tool C-3608
A little further into the section about height adjustment in the FSM for
1960 is the section of how to adjust without tool C-3608.

Look at section 'b.'
The measurement is pretty straightforward and very easy, it is just a
subtraction from two simple measurements with a margin of difference
between either side. Unless you have a perfectly flat surface to work on,
it isn't precise but you can get close enough. Of course the Master
Technicians Service Conference reference book on Suspension and Front End
Alignment for 1960 is a good read,

I used my paved street as a basis point when I levelled my '64 Crown
Coupe, opting for the highest allowed subtraction. I have a preference
for a tall sitting Imperial.
Suspension component wear, specifically bushings that have disintegrated
and worked their way out can cause a slight drop in ride height. I wonder
if the mysteriously sunken Imperial mentioned recently lost a lower A arm
bushing? It's a stretch but I've had one work it's way out of a Chrysler
before.
Measuring bumper height is not the official way of determining proper
ride height, and being such, it doesn't ensure the proper geometry that
the former Porsche engineers that Chrysler hired for suspension
development intended. If anyone has more info on that suspension team,
I'd love to read about it. Bumper height measurements would indicate if
the front of the car has a twist in it or that the bumper is out of
alignment but it is pretty remote from the official suspension
measurement.
KYB shocks, or any gas charged shock, will provide a lift if your rear
springs are sagging more than you'd like. I've posted the KYB Truck & Van
Division HD shock part # and I think it's in the repair section under
Suspension in the website. I put these on a '72 Newport of mine years
back, I'm presuming they would work for a like year Imperial, and maybe
earlier models, but that should be double checked. They lifted the rear
of that A-35 Trailer Tow Pkg with HD suspension (ie. extra leaf et al)
Newport to what I imagine to be a like-new height.
Speaking of rear suspensions, there is a fascinatiing bit in the Master
Technicians Service Conference reference book for 1965. It descirbes the
engineered rear suspension understeer incorporated into the action of the
rear spring hanger, effectively making for a bit of rear steering

Chrysler didn't just slap leaf springs on our cars for no reason. These
are an engineered item with a specific purpose. It's no wonder these cars
hold a line in a curve so well, as I'm often demonstrating to myself just
for the thrill of it ;-)

Thanks, I will look forward very much for the results of your
measurements
of the bumper height!
I think you will be the first with those figures :)
