For those of you (if any) that are still hydraulic ...

Shortly after I bought #1631, the pump died. I went to the library (this
was 1993) to research convertible top motor manufacturers for the auto
industry. I did this out of ignorance of the club, Tanner, and the air
system. In the Thomas Register I found an ad for Hypac and it had a photo
of a unit that looked exactly like my original. Ultimately I bought two
units and I think the only difference on the outside was 3 mounting legs
instead of 4. So I had to drill another hole in my mounting plate. The
second unit I mounted using a fire extinguisher holder. It wasn't an
elegant solution but it allowed both units to live in the existing eqpt
well with no mods to it. I also squeezed in 4 relays, two Twindows
electronic modules (alarm components for window roll-up), and some
additional wiring. One day I'll have to draw up a wiring diagram!
I talked to two helpful guys that may or may not still be there; Tom Hill,
Tommy Lambert. The unit I bought was a 12V intermittent duty,
bi-directional, 1/3hp, 3/4 GPM (gallons per minute), 25 cu.in. reservoir
for $160 ('93 $s). They also made new hoses and fittings to my spec that I
routed through a new hole in the eqpt well and up directly under the ram. I
have cutouts in the eqpt well covers from the way the factory routed the
hoses. I don't remember what I paid for the hoses (maybe $70).
I did remove the latch solenoids even though the new units have a pressure
relief valve built in (the original did not). While pulling the wire for
the latch solenoid I attached a speaker wire to replace it. Now I have
speakers in the doors! Anyway .. I'm sure I wouldn't feel as much of draft
if the doors were cinched closed, but I'd rather eliminate the possibility
of warping the door. If I go over a swift rise at 70mph the courtesy light
flashes a bit. But I'm satisfied with the results. They are still slow
(about 12 seconds) but with the Twindow modules they are now one-touch
operation by either the alarm remote or the existing inside or outside
switches and cutoff when fully closed/open. And since they are fully
independent systems (I added a 4th door solenoid) one can close while the
other opens.
Had I known about the air system at the time, I would have gone that way.
Although it took allot of time and engineering effort, it was a little
cheaper in the end.

You might want to evaluate another company:

(they have cylinders with internal limit switches. I'll have to look into
this myself!)
