Use the largest PF condenser you can fit in the vehicle.
Our condensers are as good as anything you will find on ebay if not better with the non painted version PF we offrer. But of course the price is higher.

I see this model at ackits.com Part #: 12-0438C
12-0438C - PF Condenser (14 X 26) it is significantly more would it be a better choice?

I think they are better constructed.

Thanks Tim, am I going to have any issues connecting this to my existing system?

Custom Hoses are needed.

Find a shop locally that makes hoses. No one has a drop in PF condenser for this vehicle. Stay R12 or deal with what is needed to convert.

Ok. Pf condenser installed. I used u bend'em aluminum lines to customize the lines. Next question. The compressor I ordered came preloaded with oil. It is mineral oil which I do not believe is compatible with r134a. I plan to invert the compressor and drain as much as possible. What oil should I use to replace it with?

I've had exactly the opposite, I wanted mineral oil to stay R-12, and it arrived with PAG. I inverted, drained the oil out, then added about 6 oz. of oil type I wanted. Then I rotated the compressor center part to distribute/mix, then drained again. Did a second flush and drain, then added the final/correct amount oil oil.

Final question. How much oil do I put in the r4 compressor and the rest of the system. I have scoured the internet with no results. Also no underhood sticker To go off.
Thanks
