Hello 1brickshort, and welcome to Chevy Chatter II,
You've come to the right place to find info for your 27 1 ton. The amount of knowledge available from the good folks on this site is quite amazing.
You might also consider joining the VCCA. The monthly publication G&D (Generator and Distributor) is a right fine magazine, plus you'll get full access to the Tech Advisors and all the forums on this site.
Once again, welcome!
Happy Motoring,
Dan
PS Just got my April issue of G&D today
