I know what it is now, it is a plate the is attached around the exhaust, roughly under the handbrake area. There is a plate under the exhaust and above and they are supposed to be connected where they meet either side of the exhausted, but with the top plate, the nut has stayed in place, but the plate has eroded away.
Is there some way i can atach them back together easily, for example, using a clamp on the side of it?
THe bolts are all rusted up and when i touch them, they seem stubon, and all the do is flake when under pressure.
I havent got a jack, lift or anything, so something simple by just reaching while laying on ground would be greatful!
