Advice on thread sizes in the oil system of a 308 engine.

Doctorvaux

Hello, I am trying to install an oil filter canister and an oil pressure gauge to a 308 engine but the fittings are missing.

1. Can anyone please tell me the thread size and type of thread for the two oil holes in the in the left side of the block (near the pressure relief valve). I would also like to know the thread size and type of thread for the two holes in the oil filter canister.

2. Can anyone please tell me the thread size and type in the right side of the block where the oil pressure switch is installed. I would also like to know the threads in the 90 degree pipe fitting and in the little extension pipe, where the pressure sender is installed, as I need to replace these fittings, as well as obtain a T piece to provide a connection for the oil pressure gauge.

Thank you for any help.
