Hard to find brake parts.

[Tim64]

Hey Gang,
I need some help finding some hard to find brake parts. I knew I needed rear parking brake cables for both sides of my truck. Last night I thought I’d have a look at the rear brakes to see if I needed anything else. Boy do I! No actuating lever, rod, or spring. Looks like the guy who had this truck never planned on having a parking brake again. LMC doesn’t have these parts. I can find cables, but that’s it. Could one of you kind souls please lead me in the right direction? On a good note, I’m going to pick up my gas tank today and I’m ready to install it. I was hoping I could go get my truck inspected Sat, but it’s got to have a parking brake here in Ohio, and most likely everywhere else. I brought this truck in from down south and they go over out of state cars pretty well.
Thanks for the help,
Tim
