Yeah Rudy actually just made a new batch of them. You had Mcgh spindles didn't you Robbie? From Rudy I heard they are a ***** to work with but with Beltech's they haven't been that bad.. But we will see. I should get my parts in soon and I will test the brackets once I get them in. But he said he has had people install them on NNBS without any issues. But still haven't seen or heard of anyone. So this will be a project. Also like I said "IF" these don't fit. I will my brother redesign the brackets to work with NNBS. I will let him tweek Rudy's brackets.
Yessir, I had mcgaughys. I had to grind a bunch of the casting off to get the brackets to sit flush. Then the holes on the brackets didn't line up exactly straight so I had to drill out new holes. Was experimental back then, before Rudy made his.
There was a guy on GMFS called JYD. He made the first ones and used them to run 14" rotors. Then another guy on performancetrucks.net made a new set to work with the Bear 15" front rotors and 14" rear rotors, i can't remember his username (maybe supersub), but his real name was Ray and he had a LSX427 with a TVS2300 on it, SS cladding, on a badass Suburban. Anyhow, he made about 10 sets, and then sold the design to Rudy who has been making them since. My understanding is that Rudy did a solid job on the new brackets. Hopefully they'll go together easily for you. Can't wait to see the outcome!
