A/c Upgrade

hello, gotta quick question for ya. i have a 92 laser rs (stock). anyone know of a a/c upgrade kit (upgrade to r134). if so, do you have experience doing it? anything difficult or anything someone dumb like me wont figure out?
thanks in advance....

You need an A/C certified shop to do the upgrade. I have had some experience with A/C, its definetly not a beginers thing, you need some training with the equipment etc

you could say i have a fair bit of experience. i just want to know if someone has a kit, what all is involved, and what all needs to be retro-fitted. and what are people's experience with doin the retrofit?
thanks
