To begin with, I will state the obvious: Michael Kiske of Helloween. Though not strikingly same range but his vocals definitely reminds of early 80s Bruce.
Joe Comeau (Liege Lord/Annihilator) also has a very similar voice to Bruce.
Tommy Paris (stage name) of Glam metal band Britny Fox, who performed in two of their albums has some similar sounding high pitched vocals.
Youtuber Raphael Mendes does an awesome Bruce impersonation. He has his own band called Icon Of Sin.
