The Old GMC Trucks web site hasn't been added to/updated in quite some time, but still has a ton of great info that might also help with your project too. wink

That might be interesting. I went to that site - ended up in some circular links without finding the info.

Let me ask - what sort of info would I get from this decoding? My tag simply has "EC152", a serial number, hp rating (85.5 @ 3k!!!), and gross weight. It seems like there would be little to decode. I guess I could attempt to dig more (the site seems a little rough around the edges - LOL). Or maybe they are referring to another tag with some other numbers?
