Just bought a 2000 Porsche 911 cab. Still new to all this, but I was trying to fix the top because it was missing fluid in the res. and when I did that it was holding the fluid in without an issue. Well last night I went to take it out and noticed that there was the hydraulic fluid for the top leaking on the side. I opened it up again and saw that the seals on the cylinders for the top are bad and is causing the leak. At least I think they are. Any idea on where I could find the replacement for these or maybe on how to fix it. New ones cost 800 for each cylinder. Also I noticed when I bought the car the guy took out the sim card for the car saying it helped with tracking where it was and such. Thing is I can't seem to find any info on what he was on about. Along with the brake light is on but the brakes are fine, I also have no engine codes. I know I have a bit of problem but, hopefully, they are small ones I can fix.
