Depends which 9" you have and its housing ends. The small bearing axles can be done with the crown vic swap. The late big ford ends can be done with the explorer brakes. I don't know of any early big ford ends that swap directly over, but I could be wrong.

There's lots of info out there on both...

I have a 9" 5 X 5.5 with big bearings out of a truck. I plan to have Moser change it to 5 X 4.5 bolt pattern when they narrow it and put in new axles. I have heard that the disc brakes from a older Blazer 4X4 work well with a little hole enlargement and they are cheap.

Most likely when moser narrows the rear they will put on late big ford ends. With that, you can use the explorer brakes with no modifications to the brakes-they'll bolt right up. Tell moser that's what you plan to use and they will factor that into the brake spacing. Explorer swap is pretty easy..

You want to get brakes from a 95-99 explorer. You'll have to pull the c clips out of the housing to get the backing plates off. You'll want to get the ebrake cables too. You may have to turn down the axle register or open the rotors. Some of the truck axles have a larger register than the explorer. I would rather have moser turn the axle down so you don't have to open the rotors up every time you replace them..

If you have any questions let me know..

Here's a chart on the different housing ends...

Looks like the blazer ends are pretty different from the late big fords that moser would most likely use...

You can get the kits all together from lots of places. The cheapest is this:

you can piece it together for a lot less than that..

I'm running a Big bearing 9" and converted my rear to disc brakes. They sell the caliper bracket which bolt directly up alone for under $60.00 for both sides. The brackets are setup to fit GM calipers which most people opt for the 85 Cadillac Seville rear calipers because they have the emergency brake setup. The Cadillac calipers are tough to adjust but work nicely when you can figure them out. I used Lokar cables which were the easiest to install to the calipers. Do a search on Ford 9" disc conversion kits, they'll sell the bracket only. Another little trick I found on Big bearing rearends is to use the axles from a Scout or Jeep, the axle are .5 inches shorter than the stock axles in the 9 inch Ford and are interchangeable. Works nice if your going with wide rims and need the additional .5 inches of clearance.

Mine was done with weld on brackets(speedway motors)"$9.99, rotors from the front of a 85 jeep cherokee $10.00 for 2, 2 new metric calipers $20.00 from napa.Total for rear disc brakes $39.99 but no parking brake which is easily solved by installing a shutoff valve in the rear brake line, just push the brakes shut the valve rear brakes stay applied.Works just like a line lock only manual instead of electric.

Where do they sell the caliper brackets that bolt on using GM calipers ?

Here's a couple that have a good kit.
http://www.tsmmfg.com/2500.htm
These are the guys I purchased my kit from and the kit was easy to install. I believe the owner is Dan? or Dave? He will sell you the brackets only and he's real knowledgeable about the subject. Good luck!

Thanks to your chart I have discovered that my 9" has the preferred new style big ends. I thought all this time that they were the old style. That will save me $100.00 at Moser ....

I now have another issue. The housing ends on my 9" look like the new style ( Torino ) but the bolt pattern is the old style big bearing. It has the 3/4" tee bolts and measures 3.556 X 2.375 . The new style ends say 3.557" X 2.0" . What am I missing here ?

Did you measure everything? In looking around for more charts to see if the early bigs had that same look, I found that the early bigs are actually 3.50 wide and not 3.566 like the chart I posted. Are yours actually 3.566 wide or did you just look at the vertical measurement? I don't know if they made the early large bearing ends that look like the lates. Maybe somebody else can tell us, but I would go by the measurements and not the look.

Did you ever say what this rear was out of?
