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!
