dont' know about where to get the sets, but the wifey's 92 535 freon just leaked out after a spring re-fill, and expansion valve replacement.
Turns out indy didn't get all of an old o-ring removed, and the new o-ring didn't seat properly. It was a no charge re-fill on his part, but thought that you might not want to experience that same issue as you probably dont' have a 10 gallon can of the juice laying around to cya.
good luck
let's see your touring. looking forward to replacing my front clip next week, and going to get the back hatch repainted, some scratches sanded out, and chips and dinks touched up...then the full on Mcguires...for about $4 fitty
If only I had some T-stars
