[200q20v] A/C compressor broken, R134 conversion?

[Joseph Vanzeipel]

Well, my AC compressor has gone south.  No pressure in my system either (I
figure the two are linked).  Well, luckly, my brother's car came with a
spare compressor (032 206 805 A), and his car is a 1990 100.  I am wondering
if I can use the compressor as a replacement on my car.  And how much or
what parts are involved in a R134a conversion?

TIA,
