[JM 35 Sedan]

Not sure if you are asking about tools made by or for FoMoCo and/or tools that someone has personally made themselves to use while working on their Early Ford V8? The tools I like the most are the ones I have made myself.
Hub/drum puller, steering wheel puller, pinion and pinion bearing removal tool, press on timing gear puller, distributor bearing removal and replacement tools, oil seal installation tool for torque tube and axle housing, tool for removing outer race bearing in axle housing, intake mount engine hoist plates, adjustable angle exhaust mount engine stand adaptor, exhaust mount engine storage stand with wheels, spring spreader, Stromberg carburetor throttle bushing removal and installation tools, bolt on engine block legs for block transport or storage, and probably a few I can't remember at the moment. I guess I enjoy making tools to work on my early V-8's almost as much as I enjoy owning and driving them.
Out of the above list, I like the hub/drum puller and the adjustable angle exhaust mount engine stand adaptor the most because I use those the most.
