TXV Tube

I haven't forgotten, I just have to dig that box out of the pile. Are you using the original R-12, or the modern R-134? I know R-12 is available for a King's ransom, but it's cheaper and easier to convert to R-134. If you've replaced all the lines, and a rebuilt compressor, a new TXV won't care, and you'll be money ahead in the future. I think I have an old RV-2 compressor in the shed. Good luck on your project.
