C20 2wd leaf spring 72 rear brake adjuster arm
I am trying to finish work on my 1972 C20 brakes, and it does not appear that they make an automatic brake adjuster arm for leaf spring trucks. The ones I see are for coil spring trucks, and they are smaller. Does anyone have one or know a source for new ones? I will try to rob another differential I have if I can win the battle of decades of rust and get it apart.

Re: C20 2wd leaf spring 72 rear brake adjuster arm
Can you post some pics? Those parts are common as dirt and should be readily available. A couple of years ago I went through this with parts that were "boxed wrong", in parts store lingo. I don't think that coil Vs leaf springs make a difference, but I can be educated.
I have a Dana 60 differential. What do you have?

That arm is not available, some people say the strut is available but I haven’t seen it. I sell the arms and struts all the time, same story on the 12 bolt rear ends, not available.
I have one set left for a dana 60, 2 struts and 2 arms, $60 shipped. |

Re: C20 2wd leaf spring 72 rear brake adjuster arm
All those brake parts are still available if you know how to look for them, the key is being able to find the factory part numbers. Amazon has the struts and the adjusting levers for like $10 delivered. Don't mean to step on any board members toes but that's why most good mechanics wear steel toed boots. https://www.amazon.com/Dorman-21149-...let+C20+Pickup Heres the "LEFT" adjusting lever, note that they are left right specific https://www.amazon.com/Raybestos-H25...let+C20+Pickup, You can use Rockauto.com to look up parts and part numbers. Amazon Prime is a great tool as well...Good luck!

Re: C20 2wd leaf spring 72 rear brake adjuster arm
They absolutely are Randy...I rebuild rear axles and front's for my 4x4 and drag racing buddies. Both my 72's have the 12-bolt's. Carlson and Raybestos as well as Delco/Remy/Moraine...Google's your friend, make em earn their money. I've had good luck using Rockauto's data base, in fact, they should pay me for correcting and bringing flaws in their data base to their attention. I just finished an 83 GM Dana 60 Front, little stuff like king pin gaskets, bearings, and seals was fun locating at reasonable prices. I also use fleabay quite a bit and have established some excellent trustworthy sources there as well...

And if you think that k-Martish dormant 21149 part is the same as these originals your fooling yourself. Here is a picture of the correct parts for your reference for when you don’t find the levers on amazon, rockauto or whichever.

Re: C20 2wd leaf spring 72 rear brake adjuster arm
Thanks for the posts. Some of the links take you to the same place I stared when I was just going for new ones. My main suppliers only had the arms for coil, not leaf. There is a difference on this differential. I finally got time to tackle two other differentials. The first one came apart easily...to easy, as I probably sold the brake parts to a customer a few years ago. The second one was a tough go, but I got it apart. The attached shows what I needed. I will get back to finishing the brake work, now that I have taken the grandkids fishing as promised.
