Few Problems W/ 89' Corolla Sr5

[|PuNiSh3R|]

I am having trouble locating a GOOD replacement factory sun-roof panel... one that isn't rusted.. I'm not looking to buy from the dealer as that will cost me... well I could put a rocket into space for cheaper :)

I am also looking for performance parts.. better (bigger) carb.. right front parking light .. new hood.. I am in eastern PA.. so um.. I really ain't looking to have a hood shipped.. but anyway.

Also the AC is bone dry.. needs to be charged.. I am qualified to do this except the fact that it isn't exactly easy to get my hands on R-12.. so I was looking at possibly R-22.. which runs the same as R-12 .. runs better.. I've used R-22 in your standard refrigerator compressors.. which are designed for R-12.. and it runs excellent.. except we aren't dealing with a hermeticly sealed compressor in a car.. and I haven't delt with much in the way of automobile systems.. Propane also works very well.. it mimics R-22 almost exactly.. Wondering if anyone has tried this.. I would if I knew there were no leaks in my system..
