Hi all, I’m doing a restore on an early Perm. I need some info if anyone can help. I need a thread adapters (see pic) for the leg sockets to step down the thread size from the original ShoBud leg thread size to the more modern, smaller thread size, but don’t know the sizes to and from. Does anyone know this? Thanks much!

Modern legs are 1/2-13, the old sockets are likely 3/4-10, that size was used a lot in the past. McMaster-Carr has a smorgasbord of different options for adapters: https://www.mcmaster.com/threaded-inserts/.
If the old threads still exist to some extent, a solid thread-locking style is probably the best option, not a heli-coil. If the old socket threads are really loose, a glob of JB Weld on the outside thread when you insert them should hold them nice and tight for a long time.
BTW, did you ever acquire the full set of matching wide pedals for the other PP project?

Do you have the original legs? Why change?
If you want to use new legs, even though the clutch will be different in appearance, you can swap threaded inserts and use your originals.
Alternatively, you may machine new threaded plugs to match the original, or cheat by buying four bolts with threads that match your Permanent endplates and eight nuts. The bolts should be long enough to have an appropriate amount of threads exposed after two nuts are fully twisted on to the bolt shaft. Jamb the nuts on the bolt heads. Epoxy in place. On a lathe turning in reverse, matching the bolt heads and nuts round to fit inside the leg tubes.
I suppose you could have the large turning in standard direction if you “dust†the heads and bolts, meaning take light cuts. I suppose you could also tighten the bolts and pin the outside one so it would not loosen even with heavy cuts while being made round.
If you have no access to a lathe, the options I give may be performed by any trained chimp in a machine shop. So simple, I have done it.

| Thank you Chris; I don’t have original legs. That would be preferable, but I don’t have that option. |

Then you can make plugs to match your Permanent leg sockets, or as mentioned above, get -- not helical inserts -- but threaded inserts that have a hex head like a bolt. They have the threads of your Permanent outside and your new threads inside. If McMaster Carr does not have them in your Permanent thread pitch, i would recommend having new plugs made or buy legs from the guy on this forum who makes custom legs. I bought a set of adjustable Fender 400 legs from him years ago. I cannot recall his name, but someone here will.

I made my own adapters.
I took a 3/4-10 bolt, cut it off, drilled out the center and cut threads for 1/2-13.
