External oil filter - question on oil lines

[Burt Lake Barn]

I have mounted my external oil filter on the firewall and will need to buy flexible oil lines with the correct connection ends. I know that Ford used different types of threads etc. and so I’m asking for some advice. Don’t want to get the wrong parts. I do have the restrictor fitting already. Also, I have not seen anyplace that offers the flexible lines pre made for the flathead so if anyone knows of a good source, I’d appreciate hearing. My flathead is a 1949 8BA.
