Will the blazer brake upgrade work with 15" weldnprostars?

I've got 15" Weld Pro Stars on the front of my monte Carlo SS. I have seen some cases where they run on 15" wheels and some cases where they don't. I do not want to run a spacer. I know there are a ton of threads about the swap I figured asking would be easier than going through all the threads Soni apologize for that. Thanks in advance

The wheels that were on my car were 15s with 3.75 BS. They didn’t work. But I was going with 17s so in my case it didn’t matter. It may depend on your BS

I'm using them with 15" steelies and there's no clearance problems. Steelies may be thinner and have more clearance than certain alloy 15" wheels.
