Longer swivel studs - sources?

[CarlTuesday]

Anyone know of a source for longer swivel studs (for wood/synthetic)? I'm doing a diy arca Swiss plate mount and need 1" or even 1-1/4" long vs the standard 3/4 or 1/2.

Bueller? Bueller? Further research indicates what I'm looking for might not exist.... Yet

They make some that are 1" long machine threads, you'd want to bed an insert nut in your stock to receive them (which would be more secure than a wood screw type anyways).
