Anyone else had problems replacing a turbo on an explode?

I took mine into garage last week for Turbo replacing as its smoking badly garage ordered a turbo in for 2005 T5 so thought all should be good. I get there to be told that when they started stripping the car down they found that the cooling pipes and the oil pipes on my car are larger than a standard T5. I was also told they were having issues sourcing a turbo as most places were quoting 12-£1500 for turbo alone without fitting and quoted a 3 month wait for parts . They have now managed to source a brand new turbo through AET I think and that will be £1048 all fitted inc vat.
