I took a chance on some impact torx sockets and snapped the only one I needed within a few minutes.
That wasn’t unexpected considering what I was working on.
I was trying to get the hinges off a CJ7 windshield since some people want orginals. On the project 7, I went with stainless steel.
Next time I’ll have some propane for the torch and a charged up DeWalt grinder. I think the bits are still under warranty.
REpeated thermal cycling along with all sorts of PB Blaster type application generally helps.
Moving out west helps in minimizing rust seizure.
Basically disassembling your new vehicle and applying proper joint fastener lube also helps in the long run.
Hind held Impact drivers. The (newer) one I have from HF works fine.
