164 A/C Modifications/Improvements

I posted this issue earlier in the 164 Technical section. It may be adaptive to some other models as well. So I am adding it in this area as well.

I have a gross leak in my 164S A/C system somewhere. I have not found it yet but suspect the evaporator core has failed.

A question before I tear into it: Has anyone tried replacing the expansion valve/pressure regulator system in their 164 (or other car with this type A/C system) with a more common orifice tube system? I did a search on the bb and didn't find anything like this.

Any thoughts about this conversion? Would it work?
