Mopar 440 oil pickup tube

Hi everyone. I got a 73 cuda with a 440 and the milodon 6qt hemi pan 30760 I believe. I tried 3 different milodon 18660 pickup tube and they just wont thread in. So I would like suggestions I tried a die but can't get it lower because of the lip on the tube. Also this seems to work but the threads are toast and I can't I'd it. Notice how it goes to the right. Thg he melling 63-s3 the head goes straight and this one turns right. Please help
