[urq] Help needed on UrQ 134 AC conversion.

[Bob]

And here's an an example of YMMV. I had 2 4000Q's that I converted. One 
was done right. All the seals, oil, receiver/dryer etc. Worked great! 
The other was one my mechanic said "BAH, just put in 134". Well I was 
selling it anyway, and the new owner agreed that it was OK to do that, 
so I went for it.  Turns out, I wound up keeping both 4000Q's and to 
this day (5+ years later) both AC's worked like a champ.
I did sell both 4000's a few months ago so not sure how they are now, 
but Im guessing just fine.
