I have an '89 E350 Cabriolet (van front, fiberglas dually rear). It turned 100,000 kilometers (60,000 miles) quite recently. It's currently a 2 wheel drive & I want to convert it to a 4 wheel drive. To accomplish this I need the 4x4 front hubs, as I have the entire front axle etc from an '91 single wheel 1 ton, but I want to be able to use the same dually style rims on the front end after the conversion. I recently found a set of the required hubs (BUDD 105427) but I'm using them on a '91 F250 that I'm customizing. Does anyone have a set of these hubs laying around, not being used?
