I am assuming you mean an AMC model 20. And I am also assuming that you mean caliper brackets. If so. There used to be someone on ebay who sold a "wooden" template. I found a link through this forum that gave me a CAD drawing of the bracket. http://www.abeenterprises.com/files/...ke-Bracket.pdf I then had a local machinist make me a set. Turned out very nice. As far as buying the brackets pre-made for the Nissan conversion. I don't know bout that. Do a search on this forum. You might just find what you are looking for.

Later

I got a set of stub axels from a 300 zx and cut the caliper brackets off and used them. I was able to use three of the four AMC flange bolts to bolt them on vesus the 2 bolt version I have on seen other AMC20 disk brack conversions. I think I traced a template for that cut off caliper bracket on a box in the shop.

I got the stub axles complete with calipers at a parts yard really cheap. I also used the flexible brake lines and brake line clips from those stub axle assemblies.

I bought the Suzuki rotors new for like $20 a piece, not worth pulling those, get new ones.

The drawing shown in the PDF is a little wonky. I tried drawing it for my own reference as I hate trying to do layout from Cartesian drawings. The missing information is the location of the center for the other large radius. I'll quickly throw a drawing together as the one I have is on my work system, watch this space.

As for alternatives, re-mans are a good option if you can't locate in yards.

Just curious... how do the Nissan calipers attach?... Are those two caliper mounting holes threaded?.. or just smooth holes?

Reason I'm asking.. I just picked up some 3/8" plate. Next time I throw a sheet onto the plasma table, I might try hacking out a few of those brackets. With 3/8" plate, I just "pierce" a pilot hole and drill out to the desired diameter. I'm assuming the .393" dia mounting holes are metric (too lazy to look)? That's why I was asking if they need to be tapped...

If I cut a set of these, I've got an AMC 20 housing in my shop I can check the axle fit with.. if I can verify the caliper mount/position, I can go ahead and do a small run of these brackets.

This isn't something I'm planning to do overnight.. it'll be awhile before I have the time to mess with them. Just looks like a fun project.

I also plan to hack out my own caliper brackets for my Scout D44 (I know.. these brackets are a dime a dozen already) using El Dorado Calipers and CJ front rotors.. I happened to have the rotors laying around and found fully loaded calipers on eBay.. so I figured it'd be fun to do a disk conversion for my CJ5.

When I get home tomorrow I will take a picture and show you how they attach. As I recall just two bolts/nuts, I had to put a few spacers in to get the calipers centered on the Suzuki rotors.

I got mine off of a 96 Maxima, they measured very close to the 300ZX. I didn't drill the two Nissan mounting holes until I fit them in place on the rotor, then marked and drilled.

They are straight through, slightly larger than my 3/8 drill bit, I ran a round burring bit on my die grinder through the hole after I drilled and it was perfect.

ACAD,
I am pretty sure if you can just blend in something close on the big radius, it will be fine. That radius is clearance for the caliper to slide. Plenty of clearance on it. The smaller radius is to clear the axle tube.
If I remember right, I had mine made to 3.1, instead of 3.05. Little more clearance. And made holes 10mm thru.

Also. I had to buy the caliper brackets too. Then these bolt to the CAD bracket. Your part #'s are right. But without brackets. Gotta have em.
Ask me how I know.

Good luck

Well since I draw for a living, wonky drawings piss me off. I spend too much time making sure the math works for the CNC to cut and the fabricators to build so when blatant things like that come up I just get cranky.

So as promised, the fully dimensioned AMC 20 to Nissan caliper mounting bracket. If anyone wants I can send you a digital print to load into CAD/CAM software.

And to stave off any questions, the dimensions are laid out assuming the builder is using a scratch awl and compass on plate. Thus all intersections are in plane. If you need a more traditional nested dimension plan let me know.
