what are these 2 parts I found in my 69GTO?

the round one is rubber, the other is steel

One on right is rear frame to bumper support...

Left looks like a rear spring isolator, goes on the upper coil spring to body perch.

x2 with robz on the other.

thanks - I need a lot of help

I love "what is this" posts, and have posted many myself - keep 'em coming!

uh oh..........

The metal piece almost looks like the piece that goes to the back of the frame next to the coil bucket / crossmember there, but I believe that is welded in.

If you find a unique large thick square threaded nut, it bolts on the small end of the bracket against the frame. The nut will probably clean right up. I wonder if mine is stainless steel because it looks like new when cleaned--unlike the other bolts/nuts which may need to be replated.

And those spring isolators have been reproduced, unlike the square nut.

I'll look in the bag of hardware marked "unknown" because it's not in the rear bumper bag.

thanks - Dave
