Some say they were available and some say they weren't, but it seems that somehow, some were out there.

I really don't think any M's left Pontiac with 12V-71's in them. Since a 6-71 was used in the MI-9500, a 12V should fit considering the 12 and inline 6 are the same length. The only fit issue I can see would be the air compressor which on a V engine usually is bolted to the timing case at the rear of the engine. Guess you would have to use a belt drive compressor on the front.

Another GMC 'unicorn' is the tandem axle Steel Tilt 9500 with an 8V-71 in it. Both the 6V-53 and 6V-71 were used offered in Steel Tilts as regular options, but I have been told there were some built with 8V-71's for auto haulers, notably Pacific Motor Transport on the west coast.
