A/C line fitting thread/pipe size/spec?

[MonLand]

The metal portion of my A/C tubing (drier side) has rubbed and has a hole and needs to be replaced or repaired.
Does anyone know the size of the thread/tubing so I can order a replacement (custom lines will be cheaper than OE replacement it seems).
(If that matters, and,, it might, this was the A/C OEM setup of the 1995 D90 NAS)

My limited understanding is AC hose is #6, #8 and #10 in size. The size at the drier I don't recall but it is one or two of those three. The threaded fittings are universal, I believe. May I suggest using E-Z Clip fittings and hose, no crimping required! Summit Racing has the full line: https://www.summitracing.com/search...tch&SortOrder=Ascending&keyword=e+z+clip+hose
I replaced all crimped lines on my 110 with the E-Z Clip system, easy peasy, and you can cut the hose to any length required.

I just worked on mine. Typically, from lower condenser to drier and from drier to expansion valve is #6 (Liquid lines). From top fitting of condenser to output of compressor is #8 (high pressure). From evaporator to suction port of compressor is #10 (suction hose). Some old applications (not necessarily Rovers) will have #12 in lieu of #10, but I haven’t seen it.

My Cool Air Logan set up uses a proprietary style connector at the driers and the are like $159-200 to replace. Couldn’t find a cross over. Converted the #6 connectors and I’m using standard Four Seasons #12 drier. Working great, ice cold.
