I have a 69 Z28 and I am trying to replace the rear leaf springs. The six bolts that hold the front brackets are spinning or stripped. Is there a trick to removing the brackets when this happens.

Thats a tough one. You need to get inside the area where the nut is, basically each 3/8" bolt goes thru a j-nut. the original ones actually have a nut welded to the j-nut clip, the aftermarket repros are a one piece stamped j-nut with no separate nut.
You may have a couple where the nut has separated from the body of the j-nut clip, you may be able to keep those from turning with the tip of a flat head screwdriver thru the slot where the j-nut is installed.
For the stripped ones, sticking a wedge between the bracket and the floorboard may allow you to back each bolt out.
If all else fails you may be able to cut the bolt heads off with a cut-off wheel or grinding the bolt heads down, or even drilling the bolt heads off.
I'm pretty sure they're 3/8" diameter bolts.
Good luck.

If you unbolt the spring from the front bracket you will have more room to work. You may well find yourself needing to cut off the heads of the bolts so you can get the brackets off. Then you can fish out what's left of the original j-nuts and replace with new.

you can't get the nut and bolt that goes thru the front spring eye out without dropping the bracket first.

Thanks guys I will try the screwdriver or wedge first. If that doesn't work I think the drill might be the cleanest procedure.

Have someone that knows how to use a torch melt the heads off the bolts. Common problem.

Don't replace the clip nuts with anything but the "CIP" branded ones. AMK sell them.
OER packaged clip nuts are rubbish.

I got them out. I drilled the two that I couldn't get the angle head grinder on. I bought the bracket and hardware kits from Firewheel Classics. Thanks for all the help. Have a safe and happy New Year
