Found it! T-nuts

[Paul]

Looking for 4x T-nuts for Bally/Williams Transformer mounting. These are the larger type, Rather than the smaller playfield type.

Anyone got any i can buy??

Cheers

Paul I just sent my spare ones to Newdos. What I actually did was get metric ones from a local fixings place and enlarge the cab holes a fraction.
