Remy,

Just one caveat; I'm assuming you still have the stock setup? The only real issue would be if you've done a conversion and are using an R-134A compressor (like I am). The original SD510 and SD710's are designed for R-12 and mineral oil.  One thing I didn't mention - barrier hoses. If you do/did choose to go with R134A, you really need to replace all your rubber A/C hoses with "barrier" hoses to keep the R134A from leaking out through the hose material, and you'd need to replace the TXV (at the evaporator) with one calibrated for R134A.  Not a lot of "win" in that situation if you're keeping stock components.

BTW, I've had pretty good luck with Arizona Mobile Air (Ackits.com) if you're here in the Phx valley.
