I'm working on an axle swap in my 1949 Dodge 1/2 ton pickup. I've thoroughly worn out the stock rear end and have found it likely that I can switch to a newer axle more inexpensively than I can repair the many issues in the old one. I found a Chrysler 8 1/4 inch rear axle from a 1991 Jeep which is so near to a perfect fit as to be unbelievable. The ratio is just a bit higher than stock, which I'm hoping will bump my top speed from 55 to 60 mph. My biggest concern is that the stock Jeep brakes are 9" drums with (I think) 13/16" bore cylinders. The original brakes on the Dodge are 11" drums with 1 1/8" bore cylinders. I'm wondering if there are any options for installing 11 inch brakes, or perhaps larger bore cylinders to 9 inch drums? The rest of the braking system on the truck will remain unchanged, so I'm hoping to find something that will be reasonably close to the original in terms of braking power, or at least not reduce the effectiveness of the brakes.
