I've been following and I think your doing it right, And you'll have a lot of fun. One thing ,on the front cross member ,I run the tube thru both sides like you did. I weld caps( plugs) in the ends. I weld a nut on the inside and use it for my friction shocks. I ran a cheap altered a few years ago. I sold it because although it was fun ,it seemed the full suit ,full helmet ,shield ,gloves and arm restraints got to be a pain. Damn hot also when your waiting in the staging lanes when they have trouble on the line. It mostly requires someone to help and a lot of times I went to the races by myself. Keep up the good work.
