I am under the impression that the washer told the assembly to install front sway bar.
The fab guys put extra time and effort into the welding of 340 K members and put that washer on it to identify it.
72 Swinger 340 spcl, auto, drums, sway bar, front & rear torque boxes - washer
Not sure if torque boxes have anything to do with it, but why not see...
Or maybe its a 3/8 flat washer to identify 3/8 fuel delivery system?
There was some method to the madness, thats for sure.
though the only cars that got 3/8 fuel line were the hemi and maybe 6bbl cars.??
Observation... I might be wrong, but isn't a 6 cyl K-member totally different? You can't drop a V8 into a car that had a 225 - wasn't there even something slightly different between a 318 K-member and the 340 before '73 ('73 and up changed the motor mounts). Would the washer thing have something to do with that if there was a slight difference - or was I dreaming about the slight difference between 318 and 340 mounts.
Correct me if I'm wrong...
That difference is in the engine mounting clip(s) and not the K.
