Hi all, I'm in the process of replacing the TXV valve on my 1959 Thunderbird. They unfortunately don't make a direct replacement, so I needed to use one from a 1985 Thunderbird, FOUR SEASONS - 38725. This TXV fits a ton of 70s-90s cars and is flared on the inlet and outlet size.
My question is, is there a drop in TXV screen that I should be using? The new TXV did not come with an inlet screen/filter like the original and I can't find if I need one or not. The system has a separate receiver/drier/filter.

Re: 1959 Thunderbird - TXV Valve Inlet Screen Help
Screens are available that you can install in the suction line to prevent debris from entering the compressor. I'm not aware of any screens that can be installed inside the inlet port of your TXV, other than TXV's that already come with them factory installed.
At some time, did you have a catastrophic compressor failure? If so, and you're concerned about debris still being present in the system, a suction screen might make sense. They have their pros and cons.

Re: 1959 Thunderbird - TXV Valve Inlet Screen Help
Thank you for that thoughtful reply! It sounds like you're saying that not all TXVs need an inlet screen, am I overstating that?
I saw the UAC ex10362C, is this something (if it fits) I can run in the inlet of the TXV? I guess my main concern is the TXV orifice getting clogged over time.
The compressor that came on the car (Yorke style, two piston reciprocating compressor) has an actual crankcase, which requires oil, and mine was bone dry. The bad TXV that I took off, the screen was clogged solid.
