1964 GMC parking rear parking brake cables.

[Claimchaser]

Good evening guys and gals!
I have run into an issue while replacing my rear brakes. I ordered the rear parking brake cables but they require the backing plate to have a small hole for the cable to go through but my truck has two brackets, one appears to be made on the cable itself. I found a photo of what mine looks like but it is for an older model truck? I have leaf springs ,not coils in the rear does this make a difference?
