I did the swap and love it! '84 Nissan 300zx calipers and hoses, '96 Geo Tracker 2-door front rotors, 3/8" steel plate that I used to fabricate the caliper brackets. The below links were very helpful. Check my gallery to see how my project turned out.

Bringing this up out of the past as my new project has me leaning towrads this as well.

I have an AMC 20 housing that is going into a 70 Jeepster Commando. This is a blank housing, I do not have backing plates. I running into a Friggin night mare trying to find a set of backing plates in order to do this.

What I understand is you must have the backing plates since the hold in the bearsings and seals?

Im swapping in G2 Alloy Axles 4:56 gears and trussing the Wide Track 20, then Its going back to a SOA installation.

If anyone knows of a place to get cheap backingplates, or something else that would work let me know. I first thought I could just make my own with metal, but it appears the AMC 20 Backing plates dimple in to keep pressure on the bearings etc?

Only backing plates I have found so far where 100$ each, which is insane I for me just going to cut them up. Worse case, I will go back to Drums, since I found the Jeep guy has a full set of drum replacemtns that include backing plates for $350, but what sucks about that is for $300 more I could order the SSBC kit.

They are just flat 1/8" steel, after you hack up the backing plate. Copy the pattern of the outer seal.

So the area over the axle tubes where the backing plates would go is flat?

In all the pics I have seen it apppears to flange into the axle to hold the bearings in place.

But if its flat then this is a piece of cake, anyone have pics to verify this? Don't want to set this up and have problems down the road.

As it is I hate putting money into an AMC 20 but I got to much cash in the rest of the Jeepster. and SOL on finding a rare Dana 44 from late model CJ, Scout width is to long for my app.

So in essence all I really need is a blank piece of 1/8 steel, and maybe a backing plate from someone I know to mark where the holes are located.

Thanks, this gives me a better clue, I can always mark hole points with the brackets but would be nice if I could have a backing plate that I could mark hole points with then cut from there.

Might be asking a freiend if I can dismantle his 20 for a pattern.

Wish I took measurements of the center hole. That could have been helpful. The outer seal plate gives you everything else you need.

Does anyone have any good info on hooking the E brake up if you use the zx callipers? I have read some say they hooked right up others say they needed to do modification I would really love to have more clarification on that.
