Default Re: A/C R134a conversion kit ?

I got one from Autozone. It worked well on my Ford pickup for several
years.

keeping with tradition of usenet ...
i will contribute via summary and by compilation of my research
in a reply to my own question.

One can convert but there are potential problems that can be
lessened by following the outline/guideline below

To properly convert an automobile A/C from R12 to R134a one
should do a little more than just buy a R134a kit and install.
Depending n the A/C system this may work for long time or fail
prematurely for lots of varying reasons such as leaks,
contamination, incompatible lubricants etc.

These extra steps will serve to address legal environment issues,
longevity of service and produce a more efficiently functioning
system:

* * * * * DISCLAIMER * * * * * *
I am not an A/C expert.
Note this is ***just an outline*** and lots of details
are left to the individual to determine. All this
information is available through online searches.
This may not be applicable to all makes of cars.

!!! NEVER !!! force fluids or compressed air
through the A/C compressor or it may be
permanently damaged !!!!!!
* * * * * * * * * * * * * * * * * * *

0. have existing R12 evacuated/recycled by some proper R12
recovery device possibly at some auto shop
1. remove A/C compressor from car and drain all the R12
lubricant ( mineral oil )
2. flush R12 A/C lines with an A/C solvent to remove residual oil
and gunk
3. replace all the A/C fitting and compressor manifold O-rings
with the modern higher quality equivalents
4. Replace R12 service port valve/fittings with R134a service
valve/fittings
5. put about 6 oz of R134a compatible oil back into the system
(may differ from system to system)
6. re-install all A/C components
7. pull vaccum on the system
8, fill system with R134a to ~ %80 of R12 volume .
(Eg - if A/C system holds 1 lb of R12 then put ~ 0.8 lbs of
R134a)
9. install an R134a sticker over the R12 A/C sticker found under
the hood so that no one has to remember and anyone will know by
looking.

any errata or addendums welcome
hth someone
