I've got an '89 Lesabre with two loose heat shields on the exhaust manifold. Both the heat shield in the front of the engine and the one in the rear is loose. The one in the rear is very loose. I'm wondering how I can reattach them so they stop rattling. It appears, from looking at the front one that they are (were) riveted on. I was considering trying steel hose clamps to snug them up. Anybody try that? Would it be OK if I just remove them?
Thanks.
