Model: F-150 4x4

I'm in the process of a body-off re-do of my 1979 F-150 and want to install a system to use R134a instead of the current R12. The truck was equipped with factory installed a/c (big York compressor). I would like to ask what parts I would need to do a proper R134a retrofit. I don't plan to re-use the compressor/lines/condensor. I will be replacing the heater core but I have not yet cracked open the core housing so I guess the evaporator core would also need to be replaced.
Everything is accessible and I have a shop that I'm working in - fabrication is not a problem for brackets, etc.
If you can help with some recommendations on parts I would appreciate it. I assume that all the hoses would need to be made up to fit.
Use a York to Sanden mount adapter and either a Sanden or Seltec compressor. New lines and replace the condenser with a true MPPF condenser. If interested contact our staff either by phone or email and they would be happy to supply a quote for the items needed.
Tim has a great suggestion. If you decide to use the adaptor, use a laser pointer to line up the pulleys. Just place it on a pulley that is factory (water pump or crankshaft pulley) and use the dot to perfectly align the replacement compressor. Check it in two directions.
thank you for your help.
I also found this info regarding the conversion that I think also has that bracket adapter included as well:
I will contact AA for the ac help, want to do it once, do it right
Evap has never been an issue. What needs to be done is what was stated, compressor, MFMP condenser and hoses. I read many that buy these 6mm or so called PF condensers and still have poor performance. The veined PF condenser is what improves the heat load removal. If you do the job correctly with the proper parts you will have a successful conversation. They adapter plate is $50.00 so if you can make one go for it.
