I swapped to towing mirrors. Somehow my drivers side and passenger side doors are different. I think my drivers door got replaced after an accident by the previous owner. These are the mirrors I got,

The passenger side mirror was cake. The drivers side however required a lot of modification. This is the video I used for reference,
Step 1: Mark where the holes need to be with a sharpie
Step 2: Drill the holes. I first did a pilot hole on the exterior and used the pilot hole to locate the interior hole. Each support is a different diameter. I went 1/8" over on each support using a step drill. The interior holes i did 1"
Step 3: Paint the holes (one of the extra holes wasn't from me...). I used POR-15. At first I wasn't really happy with how thin it went on, maybe i didn't shake it enough. But after it dried, it was a really hard enamel paint so I'm beginning to like it again.
Step 4: I've seen people remove the studs that come on the mirror with a bolt and fender washer but I decided to machine some spacers. I slotted the bolt holes because the studs we're centered in the interior holes I made
