The trianglulated bars are the stock 74 a body bars and the cross bar is 1 1/4 tubular bent to clear the aircleaner. I used 1 1/4 x 4 by 1/4" flat stock. I drilled 2 mounting holes through the inner fenders. It does make a difference. I'm sorting out the power steering next (a little slack in the box). I have KYB's on the front and 892/893 TBs. I'm building this on the GM design..light springs and big sway bars. I'm not sure if I won't step up on the bars though. Lots of winding roads here and it's fun to drive. I'm having trouble loading Pic's.
