Thanks

Looks real close but when it sets at ride height or when the suspension is compressed the shock body will move towards the inside of the car. Is it touching now?

You could go with a smaller shock body or grind a bit of metal off the caliper. But let me ask why such a large caliper on the rear of an A body? It must be way to much braking force back there.

I would say the best way to solve the issue is to relocate the lower shock mount to gain more clearance.

I would have had this problem if I would have went with the larger 4-piston calipers to match the 6-piston fronts. I chose to go with the smaller Dynalites in the rear and have no clearance issues......

I guess i may have to relocate the shock mount which sucks,the only reason i got the 6 pistons for the rear was to match the fronts,i hate when they dont tell you things like this.

Thanks

I feel your pain man. I purchased a Moser rear end with stock shock mounts, and I also ordered a set of Baer brake for it. Since I narrowed the rear end, nothing fit and I ended up selling the Baers at a loss and ended up going with the Wilwoods.

Well this is the email i got back from Wilwood

"Thank you for using Wilwood products.

The GM A-body is usually not a problem for caliper/shock interference. It is likely you will need to reposition the lower mounting point of the shock, as the caliper mounting position is not negotiable. I would look for a way to extend the lower shock mount inward toward the center of the rear axle to ease clearance. Feel free to call or write back with any further questions or if we can be of further service on this issue."

So it looks like i`ll have to weld a tab or something??

Thanks

You could buy the adapter from KORE3 and run the calipers towards the front of the rear end.....
