Hi Sulli,
Nice to see a guy from Houston. Please be mindful of all aspects of your front suspension and especially the caster angle and toe-in. The 1949 truck steering is a decent enough design, but if you study it, you'll see it was designed to let the truck handle easily at low to medium speeds using tall and thin tires. I'd suggest experimenting with different caster shims to find what you like the best. Caster isn't something that is carved in stone...you have leeway, but you don't want it to be too little or zero. Also make sure somebody didn't do anything cute before you got the truck...count the number of leaves in your front springs (should be 8), make sure caster shims are still there and make sure your rear wheels are not taller than your front wheels (that will reduce the angle, also).
Jon
