Get BCH from blockchain.info after fork I had a fraction of BTC on blockchain.info before the 1st of August and I didn't touch them at all afterwards.

I never got my private keys (nor the 12 words) from my blockchain.info wallet (or if I did god knows where they are).

Question: if I try to get my private keys (bip39) now will they be the same so that I can get BCH following this guide http://www.coinpurveyor.com/how-to-claim-bitcoin-cash-from-blockchain-wallet/?

Thanks

Yes.

Haven't looked at those guides in particular, but I was able to redeem BCH from a blockchain.info wallet by exporting my private keys following this guide: https://bl4nkcode.info/bitcoin/how_to_export_blockchain_wallet_private_key, and then importing them into Electron-Cash.
