Default 88 replacing lumbar bladder?

Looking at picking up a nice 88
Only thing it really needs is that bladder replaced. how difficult is this to do, something I can replace or best to have an upholsterer do it.

Are you sure it's the bladder itself that's leaking? It can also be the rubber valves in the air lines at the base of the seat - in the bleed down buttons themselves. If it's the bladders I'd recommend an upholsterer and replace the foam while in there, but up to you of course.

If you are in to DIY, you can fix those yourself. There are some vids on you tube that will show the way. I am working on my 93 now. I have ordered some air wedge bags that I am going to give a try (2x Air Wedge Pump Inflatable Bag Clamp Shim For Car Door Window Lock Open Tools | eBay). I may try the build your own in the second video. Here is a picture of my old bag that I removed from the passenger seat.
