The irony here is that all I want to do is plumb in the 296 (which is not IR compliant) somewhere it doesn't interfere with the 430 (which is), so this isn't a hugely difficult or complex job, by anyone's standard - hence my frustration at the £1,411 plus vat bill.
Sounds like a trip to Derby or Stapleford is on the cards, just a shame that I can't use the outfit on my home field; ho, hum who can blame them - plumb in a 296 or a £35,000 refit on a citation??? not a tricky choice, methinks!
