I'm in the planning stage for doing a disc brake conversion on my '65 F250. I am planning for follow the instructions on the linked article. In the instructions, it says that for the swap on '65-'66 models, the spindle must come from a '74. Is there some reason a spindle from any '73-'79 won't work?

Also, I'm planning to use a disc brake spindle from a F250 so I can keep the 8-lug wheels. Has anyone done this swap with a F250 and found any differences in the procedure? Thanks.

Stay with the factory stuff so parts are readily available. Here is the guide.

Use 1973-74 spindles same king pin size. You can keep 65-66 i beams.

 

Careful, the bolt/pin location for the spindles changed sometime in 74, if I remember correctly. The pin goes from the middle to higher up. Otherwise, pretty much the same but you really need to change the whole package to be safe.

 

My 65 f100 has 74 spindles/discs under it. Not sure if the 250 is different.

 

Thanks. The Fordification article suggests replacing those as well.

 

Does anyone have a front suspension schematic/diagram for a 73/79 F250? Thanks.

 

If you do an advanced search in the 73-79 forum, I'm sure NumberDummy has posted a page form the parts book in the past. If you can't find a parts truck try" Car-Part.com " it is a salvage yard site. I think you may find that the drum brakes you have now are quite good if they are rebuilt and you add a power booster.
