I have done conversions from R12 to R134a on several vehicles, and I have done write-ups on this forum before, so you can search for those.  I a nutshell, converting to R134a will require the following:

 

1.  new R134a compatible refrigerant oil (use the same amount as called for with the old R12 oil)

2. new o-rings on ALL connections that are compatible with new refrigerant oil

3. a new receiver/dryer (accumulator)

4  new shrader valves on the charging ports

5. evacuation of the system to remove all old R12 and confirm you are leak free

6. installation of a charge of R134a.  The amount installed should be 80% of what the amount would have been for R12.

 

If you have questions, fire away.
