The R-12ac in my 71 blows very cold.

My 76 with R134 does not blow nearly as cold and cycles wayyyy tooo much.

I recommend staying with R-12 if you can.

Good luck

Roger

R134a well not be as cool as R12 for one reason, it simply needs another kind of condenser (parallel flow), I have a VERY hot climate in summer and use R134a and it freezes the h*** out of me! .. use a prallel flow condenser and R134a will be just as good.

I've got a '71 with the stock A/C, but which doesn't work.

Given the cost of a recharge with R12, and the (likely) potential cost of replacing/repairing components to get it back to fully-operational condition should a simple recharge leak out and need to be recharged again, my plan is to bite the bullet and install an entire updated R-134a-based system.

If mine still worked, however, I would NOT think about changing it over.
