3B:
Thanks for your reply. I suppose I could have been misled but, the tech article I refer to is posted in the tech tips on this site.
My truck is identical to the 3/4 ton described in the acticle, except it is a 42. This is why I saw no problem in using a 55-62 differential from a 1/2 ton.
I have found a 69 1/2 ton 12 bolt rear, with a 3.73 ratio locally so I'm gonna check that out.
What I have not mentioned is that this truck will be a cruiser/driver, not a show truck. I don't plan on hauling anything heavy, so I think I can change the gear ratio without effecting my intended use negatively. Also, our terrain here in south Jersey is pretty flat, so hill climbing is not an issue.
Any thoughts on using the 69 3.73 12 bolt for my truck will be appreciated.
