TGP,
And if mone of that works out, try calling some friends of Grigg's and mine in PA (Leid Diesel Service) 717-776-7725 Ask for Timothy, but any of them should be able to help you. Explain what you're after and they might have it in stock to ship out that day or next via UPS.
They are gurus of the 71 series Detroits. Billy Marlow and I had our 6-71's worked on while we waited last Friday.

And yeah, that *is* a beautiful truck! Would you happen to have a nice hi-resolution digital picture of it we could use in the Big Bolt calendar for next year?? Email me at

Thanks John!
I ordered the solenoid from Buick Farm with the part number provided by 3B.
They showed a picture and it's very close to the one mounted on the truck,weather it's original or some aftermarket from day's gone by.
Thanks for the GM 71 info. I will remember that.
I will try and get a picture for the calendar for you as soon as possible.
When is the cut off date?
That's a beautiful 59 850 GMC your friend has, by the way!!!
