0) empty your real BTC & BCH from the wallet
1) Regenerate your 2FA electrum wallet with the seed, select "disable" 2FA
2) Find your multisig address with BTG in it. It starts with a 3. Right click, details
3) copy-past your Redeem Script here:
https://coinb.in/#verify (save page offline for maximum security)
4) (for 2-of-3 methods, as most will be) find the 3 addresses that need at least 2 of them to sign
5) Dig your X1 & X2 xpriv keys from the text file in your regenerated, password-less, disabled 2FA wallet file. It's in plain text. Windows it's in %appdata%/electrum, mac it's in ~/.electrum. Linux is in Go -> Location and type ~/.electrum
6) Make a 2 new standard electrum wallets using the 2 xprv keys and find one of the addresses needed to sign your 2FA address in each of them.
OR
6a) Use this:
https://iancoleman.io/bip39/ or this
http://bip32.org/ to find the private keys using the 2 xprv keys you dug out earlier. (we ended up generating 10,000 keys to find ours)
7) Create your new transaction in the Bitcoin Gold Debug Console (get Hex)
Sign the transaction with the first key (get Hex)
9) Sign the transaction with the second key (get Hex)
10) sendrawtransaction "hex"
[scroll down a few posts for the exact commands to enter into the console]
