you could probably cut the studs down some but i wouldn't. it would be tough to straighten out the threads again but possible. i don't know that locking lug in particular but you should be able to find one to fit. i'll look around a bit. you could always get reverse threads hahaha that would mess with them!
what did your locking lug look like?
these seem very deep but i don't know how long your studs are
