Now, a word about the calipers.
You know there are two different ones. LH and RH. In order for the manual park brakes to work one must be CCW and the other CW.
All of my research has shown O'Rielly's, Auto Zone, Parts America and more to show these calipers in their books. Most have pics and most are by A1-Cardone. The pics and refference #'s all state 224 as the casting #. They will also tell you that the pic is for show only and not the actual part.
I have ordered 3 times from different stores and all recieved were 224.
Why does anyone care? Even if they use the 224 casting and use the other caliper internals it will not work. Each casting is made so the bleeder is on top. You cannot use two of the same castings. The lever has stops also and must be oriented correctly.
Good news is that the rebuild kits are the same since they consist of seals and washers.
So be very careful before you order sets and hand over your old calipers as cores. Match them exactly.
Once they leave the parts store you are the pooch.
The casting # should be very clear in two places and they are also marked "L" and "R".
Here is a correct 223 casting and I have the correct 224's as well.
