Thanks, I got that; If you can post a pic of that so I can compare what mine looks like, that would be greatly appreciated.

Ok, just wanted to be sure I didn't lead you down a path to the same problem. I'll take a look but as I recall it was on the order of 0.030" or so.

I appreciate that. How did you deal with the bearing protusion, btw?

As I recall, I spoke w/Moser and they weren't concerned about it so I bolted it up and never looked back!
May not be as elegant but I suppose you could use washers on the t-bolts to mock up everything before having a 1/8" shim made or machine the backing plate. You could verify the axle offset needs that way too if you choose to user the spacer.

I started mocking it up, I see what you mean about the calipers. It's a tight fit. I'm wondering what would happen if I mounted them to the rear (clocked 180* from stock)?

I have not taken exact measurements yet, but it looks like my new axle would need to extend out (increased offset?) from the housing an additional 3/8" for this to work. I measured some washers I had and found some that were really close to 1/8" to space out the backing plate.

I based my measurements on a 98 Camaro I have access to; I figured that if I match those measurements, the brakes should be correct.

In my case it was an issue regardless of which side the caliper was on. Just depends on the shape of the frame.

Thanks, I'll take some pics as I get further into this mock-up. I'm pretty certain I have a little more space compared to a Nova, so I may be able to pull it off. We'll see I guess. I'm assuming the S-10 brakes you used mount the same way, correct?

I'm thinking my plan at this point should be do what I need to do to get the LS1 brakes to work and as a last resort, switch over to the brakes you used.
