My Dart is missing the parking brake hardware in the drum. It's there an oreilly part number for it? Thanks!

their site has alot of the smaller brake items such as clips/springs etc but likely not the long lever if you are missing that which'd be a Mopar specific item. the ones from any 10" 8&3/4 & maybe even the 11 inchers would be the same but you'd need to locate a rear end or just a brake assy.

i believe the 10" and 11" e-brake hardware are size specific only. i'm pretty sure megaparts has the equalizer bar [the slotted bar that goes between the shoes under the wheel cylinder]. not sure about the pivot arm the cable hooks to though.

You might want to try Finelines. There's also a complete kit if you want everything fresh. Just a note, 68s came with two different setups. Early builds used the 67 and below which used the short passenger side cable and later builds used the cable that crossed over along the reared to the driver side.

Parking brake lines are the same 7-1/4 to 8-3/4, also everything 10" drum related is pretty much the same except for the backing plate.
