Default afc thread sizes

Hey all, been a while since i posted. My 96 dodge ram 2500 is still getting tlc a little at a time.
I am hoping someone can please tell me the thread sizes for 2 things.
1. the T fitting that threads into the back of the afc where the boost line and wastegate connect to. I need to know the tread of that T fitting. or just the hole thread, same thing.
2. The thread size for the 90 degree elbow that screws into the manifold where the plastic boost line from the afc connects.
I am going to make a new setup with steel line and drilling and tapping is not really an option so just want to know the actaul thread sizes.

also if anyone has a stock wastegate in good condition they want to get rid of let me know, mine had a leaking diaphram and would rather replace it then to keep my wastegate wired shut and line blocked. My kiddos are coming for a vacation so cant afford 152.00 for a new one atm.

thanks in advance

ok thread size of the afc housing and line appears to be 10mm or .390 ish now i just need to know what the intake manifold thread size is.
talked to the dodge dealer parts man and he didnt even know what the afc was even when i explained where it was located and he was looking at a pic.
guess when i get the wastegate put back on and line changed i may as well move the fuel plate forward and see how that feels.
