"AMC didn't reinvent the wheel if they didn't have too"
This seems to be true of Willys in a lot of areas. I was not surprised to see they are very close to fit and design

Well here we are. I received a set of hubs from BamaRogue, they were from his 66 and THEY FIT!!! I just cleaned them for race replacement Monday. I also ordered the brackets from Scarebird. They talk about a little machine work on the hubs but I will wait and see just how much. Worse case is buy his hubs. I decided to go ahead and convert now because I have no drums.
Progress is being made, even small amounts add up. Thanks to everyone that helped

Thanks to 'BamaRogue' for the hubs.
The Brakes, they are coming together. I collected all of the parts Scarebird suggested to use their brackets and had to have the hubs turned down slightly to fit inside of the Toyota rotor. I had to grind a little off of my spindle mounting plate for clearance but other than that it is all fitting together. I removed the lug bolts in the old hubs and replaced them with slightly longer ones. When I get the new bolts and put it together I will post pictures. So now my FJ3A will not become yard art, but it will take a while to finish. None of the "adjustments" were major, a little here and a little there. When you are putting an after market bracket, Toyota rotors and Celebrity calipers on a Willys Jeep FJ3A, well,,,,,,,,,, Thanks to everyone on the AMCForum for the help |

I have the newest type 3 scarebird brackets and have collected all the parts to put it together. This is going on a 68 Javelin 290.
2 things to point out: 1. No splash shield. This seems to be overlooked by everyone. 2. If you live in Canada good luck on the machining costs on the hubs. |

Parts for these cars are not going to last for ever and are dissappearing now. I realize that aftermarket conversion kits are here and probably should be glad for them.
However I have worked on Frankenbrake conversions for people who have had problems with them, and some of them hae weird problems and chasing down what fits well after the fact is a night mare unless there is a well kept paper trail as to what they consist of. And that for some reason is rarely done by the owner. So for my money alone, I will stay with the fact that late model Concord and Spirit parts are bolt on's when you can find them and while repair parts are not cheap, neither are repair parts when needed for the alternative solutions nor frankly is much of anything any more. And when I can't get anything to repair them with? I'll deal with that when it happens. |

I looked at using a complete system from a donor AMC due to not finding any parts for my 61 Jeep FJ3A Fleetvan. However when I found the AMC hub would fit then I went with the after market. I already have a parts list started to be able to maintain this little guy. As was stated Things do wear out.
Going from a bare axle to one that is almost ready to slide under and get bolted on I am tickled. I may still need another hub, not sure yet. Anyone with an extra let me know. Everything looks as if it were made just for my FJ3A |

You're going to need to tell people exactly which hub you want. They vary some in size over the years and you want them to match. Buying a pair would allow you to keep a spare, so you may wish to consider doing that. You can circumvent the scarebird kits if you wish to do the leg work. People have done so using drum hubs and free float rotors from various vehicles. Up to 13" late model Mustang brakes have been used. It is always a good idea to make up a complete list of what is on your car and keep it up to date. One in the car and several backups. |

You guys just keep educating and helping me and I appreciate it.
The hubs I have came from a 1966 Rogue (Rambler American), it uses the set 2 and set 6 bearings. They had to be turned down a little. I bought the Scarebird bracket and the parts recommended. Everything fit well and looks like a good set up for my little Fleetvan. The 10" Previa rotors are just fine as it had 9" drums and this is not heavy and not a road racer. Maybe I should get an AMC label for it, just kiddin |

To the best of my knowledge, drum spindles and disc spindles are not the same on any given car. The rule of thumb applied to updating an AMC car to a disc brake configuration was to obtain everything from the steering knuckle out when obtaining parts from a Donor Car. This of course applied to obtaining parts from a donor AMC car. If tis was not followed and the parts did not fit you ended up trying to chase parts down because apparently between certain years there was in deed parts that were different. Something avoided if you just got all that was on the Donor from the steering knuckle out. I was to be honest not aware of that because I never ran across it as a problem. I have seen responses to the question of what those changes were but I have not kept that information for my purposes. I guess I should as it may come in handy. I am still using the OEM Bendix (I think) 4 piston brakes on my 1970 Javelin as they work and I have two sets of pads for them and I understand that MOPAR used them also thus giving a second source for parts. |
