When the timing chain jumped last fall, I shoved it in the back yard, next to the pole building. I WAS hoping to avoid digging thru 3 feet of snow to get to it and measure the wb. Seems that may be the quickest way to get it.
I'm sure the frame is extended from the factory length, but I THINK it is all behind the axle. Been a number of years since I was under it so I could be wrong.
