Look up metalman on here he build an awsome looking chassis and the price is really rite. safe looking updated cage chassis is mild steel. do a search for dragmaster chassis and look for his name.
Try this guy. He used to set up at the NSRA Nationals, and I saw him at Bowling Green 3 years ago with a frame. Norm Anderson 190 Chapel Lane Canfield, OH 44512 216-726-8811 Days 216-533-5909 Evenings These numbers are pretty old, but it's worth a shot.

http://www.cornfield-customs.com/ Talk to Mike Wagner at Cornfield customs , I talked to him today and he said to get ahold of him, Tim Jones
or you could go straight to the source , Dode Martin in fall brook ca.... him and the boys still make the chassis! and they are the ones who redid the moon one after it was wrecked. If it isn't done there its not a dragmaster....
