Hey, I found some web sites and have talked with a guy who had done this. His truck looked great all this convinced me to give it a try on my '54 chevy. I have already bought a front end off a 81 c10 2wd truck. I am cleaning and preping for the project right now. I'll let you know how it goes. Though i did something evil to my back this weekend so the project has slowed a little.
