11 inch B body drum front brakes ?

So thought car was sbp because of the drums on front, but when I took the back wheel off I noticed the drum had been drilled out. mid then I took the front off and it’s also bbp. And the number on the drum was L35924, and according to the googles it’s b body 11 inch drum. So I should have big ball joint control arms ? Trying to figure out what to order to redo the front end and if just keeps getting interesting haha
