How do u fit a 300tdi air con pump to RRC

Hi all, fitting a 300tdi engine to replace the V8 in my RRC. Problem is the air con - what's the best way to connect it up from the RRC pipe work to the 300tdi pump??

Had this problem when I took the vm engine out my 89 classic and fitted a 200 tdi, got Pirtek to make up a new high pressure hose from compressor to condenser, had a trawl round the breakers for more low pressure hose and used a straight barrel connector with stainless jubilee clips to join it, made my own mounting plate, it was still working 6 years on when I sold it.
