Bought a 3” B&w with the 7” drop. Really didn’t want one with this much drop but took all the measurements and decided this is the one I needed.
I tried to research a lock and everyone has a video breaking it in two seconds. I decided to go with the 5” grade 8 bolt and nut with a twist. I drilled a 3/16” hole 1” from the head for a hairpin which can only be installed/removed by dropping the spare tire. I know a determined person can still take it but maximizes the amount of time it takes. Probably only works with the tremor because of the size of the spare tire.
