Hello EJ,
Use the kit which includes adapters for the "hi-lo" fittings. That is all you will need.
Charge to 80% of the original specification R12 charge and you should be "good to go"
Nothing else needs modifications.

You can still get R-12 on ebay if you apply for the certification. Personally I'd just change the o-rings and put r-12 back in. I always read that it cools better.

Rather than change will try the Freeze 12 substitute.

Be careful with the FREEZE substitute.
It contains PROPANE - therefore, you A/C system becomes EXPLOSIVE.
The 134 will work fine - that is if you do not have access to R-12. Be careful what you buy on Ebay - as they call it R-12 and it is a substitute. I would only consider NAME BRANDS or factory sealed containers.

Some folks claim that you will need to replace the expansion tube with one from an R134 system, too...I'm not 100% sure, but folks that are in the know have told me this more than once......Can't hurt to do it.

i know that when i did the conversion on my Silver Anniversary coupe (1978) the compressor, evaporator orifice and drier. i looked on Ecklers and the kit to convert your car has the same parts along with new o-rings, and a bottle of the proper oil for the system. it works great too.
