9 inch drum self adjusting brake SPRING (gotta be for (9 inch )

Mine are MIA and NO supplier seems to have new for NINE inch setup!! Newest old yard is 6 hrs away!!!! Hoping someone has 4 of these. Like said,that spring for 10 inch is obviously too big!
YepI IF I was made out of $$, I would just change over to disc!!
Hoping someone has some lyn]ing around!?????
I know I an just adjust them ever so often by hand!!!! Been there done it, hard to remember to do!
