[AT] was Trailer brakes now Olds engines

[Ralph Goff]

Mark, I'd guess your one ton Chevy would be newer than 1981. GM never put 
the 5.7 diesel into anything bigger than the 1500 series half tons and cars 
according to my advertising brochures. 1981 was the last year for the 5.7 
and they brought out the improved 6.2 diesel in 82 which I believe was used 
in some of the heavier trucks. And I have heard that when they failed they 
were also replaced with the Olds gas engine.
