Just got back to work on my supposedly 1956 GMC 150 since before I had internet! It's got a 288 pontiac V8 that was manufactured in canada for 1 year, 1955. Just thought would let you know,I am also in possesion of an old Motor's Truck Repair Manual,18th Edition that my brother found in a dumpster back in 1979 that covers 1955 through 1965!I look forward to sharing and getting some help myself in the future, Thanks.
