My pleasure to all who enjoyed my post.

As for a 12V-71 long conventional: I don't think any were 'officially' built by GMC. Such a truck would have been an MP 9500 ('P' denoted 12V-71 in an Astro 95/Titan 90). I know a few MH's were converted to 12V power and I wouldn't be surprised if GMC built a few prototypes, but I don't think GMC ever sold one, not even as an SEO. Incidentally all the Long Nose M series trucks got the raised cab in 1974. They also had the grille with 2 low mounted headlights.

1977 was the last year the Astro 95 and Titan 90 offered the 12V-71. The General and Bison never offered the 12V. The 8V-92's made the 12V-71's redundant in highway trucks.
