Both the inlet and outlet are on the same side. Seems like the refrigerant is just going to travel straight down the header unless there is a baffle in there

This new condenser just feels tiny compared to big thick old one.

Well in a fully designed new 134a system with optimized compressor, condensor and evaporator, I know the systems work well with minimal working fluid.

Problem is that we are adding parts from different cycle designs and who knows what the result will be.

Optimized condensor geometry does likely pay dividends. Question is if it will make a difference in a system of different other components.

Are most modern 134a systems TXV or orifice tube?

I might need a garbage bag for all this ***** before it's over

I did think about measuring the volume with liquid but a smart guy could use math... Figure out the tube length/diameter for the old one, figure the header tube length/diameter for the new one and do the volume. Then estimate the volume of the tubes on the new one.

Word on the street seems to say they work.

I'm just glad you tackled this before I got to it! Seriously, I'm pulling for you, 'cause I really don't have any urge to put an r4 back on my rig!
