Bill, we know one change was increasing the size of the bogie pin from
1-1/4" to 1-3/8", but they also drilled a deeper oil passage when they did
so. They also added stiffeners and gussets to the front lower control arms,
though front axle rating didn't change.
But what else did they do that would actually increase rear load-carrying
ability? I would expect heavier frame rails, more gussets, heavier bogie
castings, etc. But I don't recall any changes like that.
It would help to know what salvage parts might be preferred.
