I have enough 134 for the job and gages i just see a few options for oils (PAG?? Ester?? etc) in various weights whats the best for a old converted ford?

PAG46 is the most common oil used by Ford for R-134a systems.

I used PAG46. And it worked great, however the compressor will come with oil as well, but the oil depends on the freon your using so use accordingly.

It looks like you have most of the stuff ready to go, make sure to pre-fill the compressor and the dryer then put whats left of the oil in the line leading to the compressor.
Make sure the system is completely dry of all old oil and Freon, and run some flush through it. Even if most parts are new. Did the old compressor lock up or stop working? If so you really need to flush or replace the condenser in front of the radiator really well. The older compressors have nylon bushing that wear out, melt and plug the tiny holes in the condenser, then it only causes more problems in the future.

No, the system lost charge and the compressor was weeping oil from the halves and the line was leaking off the back of the compressor. whats the best method to flush the condensor and evap?? and make sure all the cleaning agent is out before i charge up the system?

Interesting reading on this topic here: Auto A/C Flush Procedure

I just bought a pressurized can of A/C flush. Then used compressed air to blow/dry it out of the system. Then pull a vac for 20-30min to get all the moisture left by compressed air out, then let it sit for 20-30min at a vacuum to make sure there are no leaks. Then charge.
