13" disc brakes for AMC's

I have already made the bolt on plates to mount the calipers to the spindle mounts. My plates will bolt on between the shortened drum spindle and the knuckle upright. The original caliper bracket might just be modified into a spacer or completely deleated. The issue is that the mounting plane of my new bracket and where the caliper needs to be mounted are not in line. I need a .45" thick spacer between my new bracket and caliper to make all this stuff line up. I discovered that I did buy 1, 1/2" i.d. shaft sleeve that is actually the thickness I need but it was supposed to one of 4, 7/16" sleeves I intended to purchase for mock ups. I will buy a few more of those sleeves if they are strong enough for this use. I do not want the calipers to rock on their mounts. I will probably start cutting up my KH discs after I get it all to work with the drum spindles since they are a little stronger. I'm still missing some of the drum specific parts such as the outer washer and the cup that the cotter key goes through to lock the spindle nut as well as the smaller dust caps. I will be looking for those items tonight since I need all these small parts before I can put them on my car. Fortunatly I do have an extra truck in case this takes a few days.

If id do run splash shields I will just use the ones already on my KH disc brakes and modify them to fit around the bigger calipers. You probably didn't have any since you only had your original drum setup. I have already converted from the original drums to my KH brakes so I have parts from both setups. Since you located your calipers to the back, like some of the modern cars, you might have to drill new mounting holes to rotate the covers to match your caliper locations. Some of these covers actually direct cooler air to the back of the disc since the outside already gets cooler air from being exposed to the air around the outside of the car. I have openings in my front air dam that I am thinking of directing to the back of each disc. Under normal street driving I doubt you will notice any difference and a dust shield that is simply a cover might actually trap more heat.
I was able to buy most of the small items that I am missing such as the spindle nuts and such but RockAuto does not list dust caps for AMC's so I had to order some based on diameter. All I'm missing now is the new lug studs.

Prostreet, looks like a different paint scheme than the last time I saw this cars progress. Did they re-do the paint or did you wind up doing it over yourself?
Looks really nice. I like the two tone color choice.
Scrap

Keep on sanding the clear with fine paper until the scratches are gone and buff. If you go through you are planning on re clearing anyway so why not try to avoid the work of painting it first. 

Some guys will probably notice that my original idea of mounting the calipers in front at a 45 degree angle will not work. The calipers are too big to mount in that location and the upper caliper mounting hole is blocked by the spindle mount upright. I decided to mount them straight back where Ford mounted them on Mustangs. There is much more room there even with my shorter spindles. The original distance from the back of the upright to the bolt face on the disc spindles was 2-1/8". I removed 3/4" off the drum spindles and completely deleted the original caliper mounting bracket. Adding my 1/4" thick brackets and my newly shortened spindles removed 5/8" from this number. I wanted to make room for my possible need for the 3/4" wheel spacers but after bolting it all together, I will only need 1/4" spacers and just barely. I still don't have my longer wheel studs and I will need to buy some 1/4" spacers so this car will have to sit for a few days. My new wheels have a 4" back space so this all makes my wheels fit in the wheel opening just like I wanted. Any more spacing would have made my wheels stick out. They currently sit back 2" from the outside of the wheel well. It took most of the day to buy more 1/4" plate and make my new brackets but I should be able to do the other side much quicker. I got a 12"x 12" by 1/4" plate from Lowes. Buying it this way cost way more than the scrap price pieces I got earlier but that place is not open on weekends and much closer to work and not my house. That piece of plate steel cost $30, but still cheaper than a $1200 kit. I will be posting a final parts list and costs as soon as the car is back on the road and tested. No I will not be making brackets for other people but will happy to provide a template and measurements if anyone wants to duplicate this setup. I don't expect to get any more days off for the next 2 months, including weekends so I really don't have the time to fab brackets.
