I did the front bags this summer. Not as bad of a job as you might think. Dennis (87MH) posted a procedure on the forum which saved me a lot of time. Removing the old bags involves cutting out the bottom schrader valve then making spiral cuts from the top to the bottom and pulling the old bag through the hole in the bottom of the lower A-arm. Seems like a good pair os vice grips and some dish soap helped.
Installing basically involves collapsing the new bags and holding them with worm gear clamps (like for your radiator hoses). Then sliding up through the hold, dropping each band clamp as you go. Partially inflate, move into final position then fill.
Do a search on the forum for front air bags and you'll find the procedure.
One tip: the PO ran a T line to a pressure gauge and a dash mounted schrader valve. I can always see the front bag pressure and adding air is a simple as hooking up my 12V
compressor from the cockpit. Very easy and way cheaper then those auto fill systems from CW.
