So far as I was aware I only asked the question in this section of landyzone, if referring to asking on another forum then when you don't get a response you ask elsewhere, landyzone used to be a welcoming and lively place, with a bit of banter... the last few queries I've made have been met with very blunt replies.
When I bought the series it had an aftermarket pump.. not the original ac type.. so was checking if anybody else was using a spacer.. I only queried it on the rebuild as there is no mention in the parts manual of a spacer nor in the big book of lies Haynes..
Thank you for replying tho..
