Backing plates

Something to note...

There was a change in the hardware around 69.

My recommendation is to look for hardware based on 69. The 10x1.75 backing plates will work with either, but the 69 has tabs to prevent the cylinder pistons from popping out when installing the hardware.


1 is 68 and older (no tabs)

3 is 69 and newer (with tabs)
