Lookin good Dipster! This might be a stupid question but what is the bracket coming off of the brake booster?
..i mean i doubt you ever have to change a tire in a hurry or anything
Minimum car weight must be no less than 3400lb with the driver.
Your J bar is good. Tying it into the main cage will help it. I never said trans member. I don't know where you got that idea. I'm talking about your front most vertical bar on the right side. (Where the passangers feet would be).
As for the drivers side. Can you bend the bar to gain brake pedal clearance and still get it forward? Do you have axcess to a mandral bender to get that done? The farther forward you can get that bar hellps big time. Thats why your rules dont alow them past the firewall. Forward hoops help that much!
