Hi everyone! I am a long time reader,first time poster on this board. I finally got a decent project truck,and I am excited to get going on it! I bought a 1970 Chevy C-20 truck today from it's original owner! It was bought and spent it's entire life in ND where I live. I have all the documentation that came with the truck originally too. Rockers are solid,wood bed in decent shape,interior is great,and other than the 1 driver front fender that is wrinkled,the body is pretty good. (at least for up here) I was wondering a couple things right off the bat....I want to lower the truck a little,put some fatter lower profile tires on,etc and was wondering if this is doable with a 3/4 ton? Also, I need a front fender and was wondering if 1/2 ton body parts are the same? and one more newbie question, what is the easiest way for me to switch to a five lug setup instead of the heavy duty eight? I have access to quite a few half ton parts trucks,hopefully alot of parts are interchangeable? Thanks in advance for any help anyone can give,and for having such a great forum for all of us who love these trucks!
