are there different style 14FF backing plates? interchangable?

[desertrat67]

I went and got a parking brake cable setup for the Sub, only to find out the cables are different and so are the backing plates. The axle I have uses two bolts on each side to secure the p-brake cable to the drum. The calbe I picked up use a round clip with three prongs on it that just pops into a hole in the plate.

Can I use the backing plates from the truck at the yard and just swap all my brake hardware over or do I need the cables that match my axle?

Here si what is on the truck:

Here is what I bought at the junkyard:

Anyone? Can I use the backing plates from the truck at the yard and just swap all my brake hardware over or do I need the cables that match my axle?

I plan on being at the junk yard at 9 am tomorrow if I can swap the backing plates. Someone please let me know if this is a mistake or not.

Yes, there are two styles, based on age, AFAIK. Older trucks (through the mid to late 70's) have the push-fit style like your bottom pic. Newer trucks (starting in early or mid 80's?) have the bolt-on style of your top pic.

I tack-welded the bolt-on to the earlier backing plate to make mine work. Alternately, switching backing plates would do the trick as well.

There are two different styles. The bolt on style are early and the clip in style are later. Just install whichever style of backing plate matches your e-brake cables. Just make sure the backing plates don't come from a dually if yours is a SRW as those again are different.

Allright. thanks guys. Both axles are SRW, so i will be going to the yard tomorrow.

ok...conficting answers

who's right...i'd have to say that the snap in is the later yrs

and that bolt on is the older style...i may be wrong, but i just went looked at mine and from what i know are axles from an 84-86 k30 1 ton(ring gear marked 84)...it was not bolted on, the plate is stamped w/ a triangular shape to it(resembles bolt on piece), but is part of backing plate and it has the spring type retainer....backing plate has Bendix stamped in the bottom part of it ..that bolt on is old school, not sure I've ever seen that bolt on type, its always been the spring type retainer, but I've always been 3/4 ton and down stuff 14sf 12b 10bt...this my 1st set of 1 tons and a ff, thats a freakin huge drum and w/ the hub attached w/studs, almost if not as big as the diff!!

I had the non bolt on style on my 88 crewcab, so i am going with bolt on is earlier. Also, look at it from the manufactureres point of view. Snap in = easier and therefore = cheaper.

Clip style is definately later style. I personally have never even seen (in person) the bolt on type.

I hadn't either, until today, and I have owned the thing for almost 2 years!!

I had this same problem. My axle had the bolt in style and the cables I ordered came with the press in style. I ordered backing plates and drums from ebay (I would just go disc if I did it all over again).

What I found from my research is 83 and earlier are the bolt on style and 84 and later are the press in style. Of course there is the typical bleed over in year changes that we see in all things GM but these are the general years of the change.
