2nd Gen AC Conversion

[SecretSquirrel]

My nephew picked up a 91 4R with 31K original miles (garaged)... unreal right?

The AC is old and bled out but is a R12 system. What does he need to convert R134 and who has what he needs?

Thanks Paul. I took a look and got conflicting info on whether it could be done that easily... for <20 bucks, I think its a good 1st step for him.
After that, I think he'll need to look for a compressor...
