1967 pontiac parisienne convertable is leaking fluid in or around the driver side cylinder.
were do I start ?
top closed
remove rear seat
remove trim
does that get me close?
Is there a better way to approach this?
Have never had a convertable not sure where to start
Thanks Greg

you have to pull it out of the car to do it properly

You are best to take the entire hydraulics out as 1 system. That includes the 2 cylinders, lines and pump. Then lay it out on a bench before trying to separate the individual components.
This way you won't get hydraulic fluid all over everything in the car. Also be careful and try not to get hydraulic fluid on your paint - it may not be too common but I've heard of people using brake fluid in convertible systems and we all know what brake fluid does to paint.
It should all come out straight forward as the cylinders are just bolted in on special pivots that thread out at top and bottom of each cylinder. The pump itself may be just in on rubber feet (plugs ) and not bolted down.
Be sure not to loose any of the fittings or bolts as they are unique.

my guess would be seal on top of cyl.
not repairable as far as i know
search online for replacement
.....I rebuilt a 66 GTO pump last winter and got everything from Convertible Service in california. Their online store is the one Lefty posted : store.convertibleparts.com . Good place to deal with.

I would see if the leak is in the cylinder itself, or only in the line. I ran into the same problem about 10 years ago with my convertible on the passenger side, and fortunately the leak was in the line. I bought a new set of lines and problem fixed. Filling the pump is a real pain, had to use a small funnel and a flexible straw to get to the filler hole.

Put the top all the way up, or half way up. You have to remove back seat and side panels. Older GM's had brake fluid in the system from factory, you don't want to get that on the paint. If you change out cylinders, refill with ATF. If the cylinder is leaking, you should replace both at same time, not just one. Otherwise cylinders might not go up/down at the same rate and you'll wind up with a problem.
Hydraulic pump/motor is under a cover behind the seat. It sits on 4 rubber grommets that push through the trunk pan. Put a little bit of lube on them and then work them out of their holes.
Unbolt the top of the cylinder ram from the convertible top bracket. There will be a nylon bushing in there, be careful not to lose. Then unbolt the cylinder from the bottom. Pull whole assembly out, fix what needs fixing and re-install. You can re-fill the reservoir before it goes back in the car. It's a self bleeding system, just need to work the top up and down a few times. If you need to add a little more fluid to the reservoir once it's installed back in the car, I use an oiling can with a flexible end. If you already own an oiling can, it's much cheaper than buying some re-filling kit.
Cylinders and pumps and pre-made hydraulic hoses are avaliable online. Check e-bay or similar.
It's not too bad a job once you get into it.

yes, take it out of the car before playing with it
my old pump had more fluid on the motor side then in the reservoir
