I'll list the sources for NOS once I know what type of A/C system the OP's truck has.

E3TZ-19972-C .. Discharge Line - Compressor to Condenser - Use with hoses connected directly to the compressor (Motorcraft YF-1099) / Obsolete

1983/86 F250/350 460

E3TZ-19972-H .. Discharge Line - Compressor to Condenser - Use with hoses connected to service valves on the compressor (Motorcraft YF-1106) / Obsolete

1983/86 F250/350 460.
-------------------------
E4TZ-19837-B .. Liquid Line - Dryer to Evaporator - Use with hoses connected directly to the compressor (Motorcraft YF-1214) / Obsolete

1980/86 F100/350 & Bronco all I-6 & V8.

E4TZ-19837-A .. Liquid Line - Dryer to Evaporator - Use with hoses connected to service valves on the compressor (Motorcraft YF-1213) / Obsolete

1980/82 F100/350 & Bronco all I-6 & V8 except trucks assembled in Twin Cities MN & Norfolk VA // 1983/86 F100/350 & Bronco all I-6 & V8.
----------------------------------------------------------------------------------------------------------------------------------------------------
E4TZ-19867-E .. Suction Line - Evaporator to Compressor - Use with hoses connected directly to the compressor (Motorcraft YF-1222) / Obsolete

1983/86 F250/350 460.

E4TZ-19867-G .. Suction Line - Evaporator to Compressor - Use with hoses connected to service valves on the compressor (Motorcraft YF-1224) / Obsolete

1983/86 F250/350 460.

After seeing my compressor and how I have the manifold blocks, is that directly to the compressor or service valves?

For the most part, by searching eBay, I can get most of those part numbers listed.

I will no doubt overpay for them, but given my situation and lack of time, seems like a viable option.

Also, beings that these were originally for the r12 system, would I be able to change o-rings and use them for r-134? Most I’ve seen are new or NOS.

I would not use r134a on a NOS hose. Most new hoses are r134a compatible hose, I would ask who you buy them from before spending any money. Old R12 hoses exposed for years to the r12 and the r12 oil will seal against the r134a. But a brand new never used NOS r12 hose is not going to be leak free to r134a.

I’m still assuming I DON’T have service valves on the compressor, therefore I would need:

Suction E4TZ-19867-E
Discharge E3TZ-19972-C
liquid line E4TZ-19837-B
