Drain plug location
I have a 74 f100 with a 66 Mercury 390 that I believe came out of a car. I went to drain the oil and found that the drain plug was on the right side of the sump and facing the crossmember. If I'm not mistaken, I believe that the oil pan for a truck has the drain at the rear of the sump. Every oil pan I find online for an fe has the side drain. Any suggestions?

I'm wondering if the pan you have could be modified by adding another drain plug at a more convenient location.

I had the exact same issue with one of mine (car pan in a '73 2wd). The crossmember has a hole in it (thanks to a blue-tipped wrench) where the plug was and it was nothing to snake the socket and extensions between the i-beams to get to it after that. Obviously, it made a mess while draining - but it's a Ford so it's normal.

Not reliably (read: without pan removal). Either a nut has to be welded on the outside or a nut or plate has to be welded on the inside to give any kind of thread engagement in the tin.

I pulled a 460 out of a dentside in the wrecking yard a year or two ago and found the same thing. Car pan and someone cut out a hole for the plug rather than source the correct pan.
I had the engine out at this point, but this is the front 2wd crossmember and you can see the hole. lol. Whatever works I guess.

Since the owner was considering changing the pan, removal would be needed anyway. I've brazed a "bung" on pans before (including transmission pans) and got the drain in a good location to make draining more pleasant.
