You can probably get away with something much smaller. If you want be able to tackle most situations this can work, but all of the bolts on the JL should be metric. If not, you might need 1 or 2 SAE sockets, but probably not a whole set. Just depends on what you need.I have one of those Kobalt tool kits from Lowe’s. Has sockets in both metric and standard along with a slew of bits. It was 100 bucks. Has something like 200 pieces total.
HF Icon sells no skip sizes or you can get the cheapo pitsburg ones and go to northern tool and pick up the skip sizes.
