My big problem is dealing with customs etc being in Canada, shipping parts down (core hoses etc) makes a nightmare. Finding local talent that is responsible for their work is another issue, it is hard enough to find someone that will work on an old car let alone custom fabrication that will actually work in the end (I used to work in a shop that did numerour "projects", the amount of bad workmanship I saw for fabbing fuel cells etc was incredible, people could not even deliver a leak free gas tank built to our dimensions, even after two attempts, same for custom turbo oil plumbing, just headaches!). I will ask around first about having house ends refitted etc before I order parts, my welding is not good enough to try on parts that I cannot ever find again around here!
Rollguy your new compressor has thread on hoses? Could a bolt on hose set up not be used like the factory set up (Delco-1982 240D).
