Thanks! I was on there before I knew this truck was an auto and I missed the info on the autos. I will be spending more time on there for sure(when I have some time).

It is not a bad combo I love people who scratch their heads when they take a look.
Nice! Since yours was out at one time what would you estimate the weight of it?

From what I read the odd gear pattern using reverse as park with the engine off hasn't been used since the early 50's. Is yours the same way?
