Probably just change the gears in the rear end but I must admit I don't know anything about the truck rear ends. Do you know what gear ratio you have in it now? That would be a good place to start. You should add your general location and email to your profile, you can never tell when it will pay off. Charlie Stephens This message was edited by CharlieStephens on 4-13-19 @ 3:53 PM

I'm assuming you have a '48 Mercury pickup(Canadian). In the glove box door there should be a metal tag which would show the rear end ratio. Most likely it's a 3.93 or 4.11. Changing the rear gears would be the best way to go. A good highway ratio for your pickup would be 3.56 or near that number. You can change the gears in the existing rear end or an alternative is to put in a later model rear end from another Ford pickup. You can use up to a 1972 Ford pickup rear end and it will be the correct width , will mount right to your existing springs and will have the same wheel bolt pattern..

It's been a while , but I think that you may need to change the rear universal.
