polar air a/c

i picked up a polar air under dash unit[dealer installed option in 1957/58].has anyone ever hooked one up to a modern a/c system?

I bid and won one on eBay but the seller never delivered and refunded my money instead.  In researching it I found that the thermostat/control on those old systems are not compatible with new compressors freon etc. so was happy I didnot get it.  Not sure if the information is true but worth checking it out.  I think I was Googling converting an R12 system to 134.

There are kits to change over the old R-12 units to R-134.
I'd start with an A/C repair shop, if none local try the aftermarket for streetrods.
Goodluck,
Ron.
