I did end up finding them sold separately at O'Reillys as an ebrake strut bar spring. I think that may not be in anyour of the kits, because it's an ebrake part???
Yes, that's the E-brake apply strut, and is part of the E-brake hardware. It will function perfectly w/o the spring if none is available, you may or may not hear the strut
rattle over sharp bumps w/o it. They are available however, so....
