Just curious what people's opinions are on the best type of material to use for something like this and what kind of welders should be used?

My opinion, if you are asking this question, no way you can do this.
Please for your safety, pay someone to do it for you.
I am with greengoblin - Seamless DOM and a TIG welded. Mild steel at a good thickness for cost reasons. Chromemoly can get expensive and it takes a more experienced welder to do = more $$$.
Agreed. If your not 100% sure about doing part of it then dont do it, and yea chromoly is expensive but i think it is the best for doing this. We did it on our race car and used chromoly.
Very true, if you add to much heat and let it cool to fast you will end up with a joint that is weaker that using mild steel.
If you where to have it fabricated for mild DOM you would use 1 3/4 tube with a .120 wall.
If you where to have it made of 4130 you would use 1 3/4 tube with a .083 wall.
Who needs a front end anyway, look at my avatar. I just have a one piece welded hood and fenders.
Minor correction. That would be 1.625" (1-5/8") diameter with an .083" wall.If you where to have it made of 4130 you would use 1 3/4 tube with a .083 wall.
My point was that 1-3/4" chromoly is not commonly found because it's not commonly used on a car. 1-5/8", however, is. Does 1-3/4" chromoly even exist? I sell chromoly daily, and I know for a fact that we've never offered such a size. And nothing larger than 1-5/8" is mentioned in the NHRA and IHRA rule books. IMO, using anything larger would be adding unnecessary weight.1 5/8 is also acceptable, but 1 3/4 is stronger.
