What is this bracket called?

you could fab one that would have the gussets on the ends and that would allow you to use an easily sourced (locally) urethane bump stop from a newer vehicle that bolts in the middle. try energy suspension for a few options or simply google suspension bump stop under google images. lots are single bolt and some use 2 bolts. a local 4x4 shop could likely hook you up with something that would work well. I like to stick with something that is a stock replacement so it will be available in the years to come. I have used the bee's nest shaped ones from S10's before. they are round and use a single bolt to mount.
