Welcome aboard Simon!
You've found the right place learn some tips for working on your truck, as a few of the guys around here have been posting about similar projects lately, so you'll have no problem finding people to compare notes with.
You live in an ideal area for attending metalshaping events too! Quite a few of us get together once in a while to shape some metal up here in Southern Ontario, and you've also got the Comstock meet just a ways south of you in NY State.
Let us know how we can help out Simon. Got some pics of your truck?
