    I've got finned aftermarket drums & 16" stock wheels- they work together OK.

    All these 11" brake kits copy the factory configuration from the intermediate Jeeps, 1972 through 1975. If you can find a CJ donor from these years, or a '72 or '73 Commando, the brakes will bolt on to your Jeep with no changes. Note the earlier versions of this application used a drum without fins, and the later ones are finned. So if you need a little more clearance for your 16" riveted wheels, get drums for a 1972 CJ. If you buy from Herm, ask if he can supply the kit with the plain drums.

    I seem to recall using finned 11" drums on my first 2a with 16" stock rims too, but I have read that others have not been able to do that.

    I'll try to get a pic in the next few days showing how much (or little) clearance there actually is.

    Patience is your friend. If you really start looking and ask any local oldtimers you may be amazed at how many old Jeeps are out there.

    Yes this is Front and Rear blacking pates/drums/shoes/hardware/cylinders, and front rubber hoses.

    I'm not sure either unless that phrase is to cover both the 11" drum conversion and disk brake conversion.

    Awesome. I'd appreciate that. I'll have to look at me rims, as far as I know they are standard 16" willys rims.

    I been looking for years just to find a old decent jeep to fix up. Most here have already been restored or have ended up in the scrap pile back when scrap stell was so high.

    There's 11" backing plates on ebay running about $40 each.

    Yes sir I seen them, unless you found some I over looked, I'd still have to get shoes,springs,cylinders,and drums. I guess I could get old stuff and use it, but I want to be sure the brakes will work when needed.

    Thanks for that info. I'll be sure to ask him when the time comes. I'd hate to get the finned drums and them have to get different rims.

    If you buy the brake kits, they will come with backing plates from the junk yard. AFAIK there has never been an aftermarket source for the backing plates. A few other parts have to be recycled too ... parking brake lever, parking brake equalizer, "links" between the wheel cylinders and the shoes. All the rest of the stuff can be bought new. These 11"x2" Bendix brakes were used on a lot of different cars and trucks. So there is still plenty of demand for the service parts, which keeps the price down, though lately the junkyard pieces seem to be getting more scarce.

    :confused: M151s use wheels that have to be modified to fit over the front locking hubs. I had 2 that I pulled NDCCs from and scrapped the wheels as useless. They look all wrong too.

    11" drums can be had from Rock auto for around $32 each all day long. It's a very common part. In fact all the parts you would need (cept for the backing plate) are easily available and very inexpensive. The backing plate is not tough to find.

    Sounds like you are just starting out. The 11" brake conversion is easy and cheap. Apparently the disc conversion is as well. Putting the 11" drum brake system on your A1 is a great upgrade and not one person in a million is going to recognize the change from stock. You'll notice, though, in the vastly better stopping ability for your jeep. Also, you don't need to worry about the e-brake parts, as your A1 has the handle between the seats and is the best ebrake system jeep came up with (IMHO)

    I'll do some more looking I know the kit from Herm comes with refurbished backing plates. And the kits I've priced with just drums/shoes/hardware run about $225-275. (This does both sides) but I'm still looking. :)

    I'll keep rockauto in mind, and yes I'm just starting out. I've fixed up and restored a 1989 F150, but this is my first jeep. It does have the e-brake handle in the middle, but it's stuck. Lol. So I'm sure the e-brake needs some tlc

    Since you're just starting out, just start with the basics. Make sure it runs, stops, brake lights, e brake, turn signals work right, fluids changed.. just get to know what you have before you tear it apart. Drive it around for a while as it is. You will see the need for better braking. You will see the steering issues. Your power issues are not the problem right now. Just get it all working as good as you can, then move to the most important things. Make it safe and somewhat reliable.

    LOL. I'm getting there. Right now it runs great, it does smoke some. (I'm going to check and see if the head oil drain ports are stopped up ) Transmission shifts into all gears, and the rear axle I know works. But the brake pedal goes to the floor (master cylinder and brake lines shot), e-break doesn't work, the wiring has been butchered so the whole jeep needs to be re-wired (I'm ordering a early CJ3b/CJ5 complete wiring harness ) and converting over to 12 volts. I'll need all switches since it's been stripped of them, as well as the steering rebuilt, rear floor panel, passenger kick panel, passenger floor board, and passenger tool box. And maybe a passenger fender. And all lighting

    I've got a lot of work to do.

    You might consider Samurai wheels to go with those 11" brakes. Same bolt pattern and the center fits the hub hole.
