According to the data book for 74 the S13 heavy duty suspension option was standard on Road Runners. It includes Heavy duty shocks (front and rear), Heavy duty torsion bars and rear springs, and a front sway bar(doesn't indicate heavy duty or not). There are only 3 sway bars listed in the parts catalog...
3402891 - all engines except 400, 440
3722411 - 400, 440 engine
3722411 - station wagon, all
3815551 - Police, 400, 440 engine

So... it looks like the small block sway bar is #3402891. The sway bar in my original motored 360cu. in. 74 has never been changed out and measures 0.940 in. (approx. 15/16 in.). I do not know what the big block sway bar measures nor the police bar. Anyone else?

big block 15/16?

Thank you.
