86 coupe a/c

[Mark Donohoe]

I've owned my coupe for about 5 years.  The a/c has never worked.  Might have a leak in the compressor.  There is a nice coating of red grease on it.  Someone may have run some dye through it before I got the car.  Anyway, I saw this 134a retrokit and want to know what you guys think. Directions say all you need to do to switch from R12 to 134 is vacuum the system and change out the ports for the 134 hoses and fill 'er up.  Can that really be so easy?  Seems like I've heard things about incompatible o-rings and hoses and what about the expansion valve and drier?  Any thoughts?

Thanks,
