Are the TTI shorties really my only option?

Huh?

I have Doug's 453's on the 340 in my Duster. Later 308 heads, 4 speed and all the linkage. I have manual steering but they clear power as well. The z-bar has to be modified, but it's not hard. I converted my own because I'm cheap and can weld. Or you could buy the one TTI sells for their long tube headers. Which also should fit.

Yeah, I could use 'em. It was the modified Z bar that put me off. Maybe it isn't a big deal, but I just wanted a drop in. Bummed already b/c I spent all the $'s on the 340 manifolds and the Accurate Exhaust............ ouch........
