LATE to EARLY 440 A/C Fitment

Hi Guys
Big Jim from Down Under
You may recognise my (Imported from your Country) 1976 New Yorker Coupe (pic)
Anywhoooo ..... whilst Importing I bought THIS (pic #2) - got it for $2k = WooHoo
TWO problems
(a) is there a Kit etc available so I can hook / bolt up my A/C (No Nut welded to Block)
(b) Scored the engine from a "Rebuilder" who went broke @ Auction, but something is NOT right = it's minimum idle etc is 13 degrees...
