hi sages- one way ive saved a ton of cash is to anticipate future problems with mechanical devices and seek out low cost alternatives in advance. when one of these peccadillos is urgent you often have to go to the cleaners. sure most of you have been there done that. anyway on the m47 i have in my 92 245: when it blows- are the parts(gears, bearings, etc) generally available to repair it and is the skill set still available in this market . uncle moe (sherman tank mechanic at omaha beach and later chrysler mechanic)tells me most mechanics today cant or wont do this repair/rebuild. in the alternative, are these boxes generally available in yards and what do they cost(guessing 250). would love to hear answers to these questions from a sage who has actually done this repair, been soaked for it or found a used box in their yard. guessing rebuild costs $1000 from a shsyster. thanks tons oldduke
