That chassis is unknown.  The rear axle is definitely a Dodge, though.  It's a 3/4 ton 4x4, and has a SBC engine in it.  My guess is either a Dodge or GM. I found out the lugs on all four corners are left hand threads. The chassis was shortened by a farmer in Idaho, and badly. Straight vertical cuts in the frame rails, and a plate welded over it on each side.  What a maroon!! I would never drive it.  

You are assuming both sides look the same.  The truck was parked next to the north wall of the shop when the fire happened.  The driver's side is completely charred, molten shingle tar melted and dropped on it, paint blistered, body filler popped.  I was going to satin clear coat it, but now, it is totally ruined. I am going to leave it as is.  It will be more of a rat rod look now.

I am going to have a capital "D" laser cut, and rivet it crooked over the last letter on the tail gate.  The project is now called Studebaked.

Not sure what side I like better , the rare or the well done side. Both sides have their own stories , ya can’t make that stuff up ! Way Cool !
