I concur. The Yahoo group is really good. Luke has also been the man with the plan. And, places like NAPA and other parts places have come thru a time or two as well.
I also have a thread on here about a rebuilder near Chicago. My humble opinion is "steer far and clear", which brings me to my point: Your best bet, in almost ALL cases, is to consult this fantastic forum for virtually ALL your questions or needs. The GMC yahoo site as well. The knowledge and help on here is second to none. There is no way I could own my bus without being on here. Period.
Long live the "Buffalos"!!!!
