Welcome to the madness KnuckleSkinner! Love those old COE's and if you found one fairly complete for a grand you "did good". You could part it out for a lot more than that but we're hoping to see you put it back on the road where it belongs. Don't hesitate to ask questions, there are a number of COE & big truck builders here that have a ton of experience to share.
Once again, welcome...and DO get some pix of that puppy.
