WOW Thanks a LOT!!!
I will definitely stay away from valves and chrome plated stuff.
As for springs, i can get some of those, i think its a lot easier to forge one of those.
I also found a bar from the suspension, its like 1 1/2" thick.
I will post a picture, of that large piece (like 1 yard long) again, i dont know wich steel it is made of, but if you said its ok i wil believe so.
Thank you every one! this is my first post, so it means a lot to me.
