I've got a custom 4" over the axle set up on my Trans am with the panhard bar relocation. On the over the axle pipe it actually sits basically against the relocation bar and will occasionally rattle. If I take a piece of heater hose and clamp it around the bar to make a bushing for it to sit on will it cause any problems like melt the rubber on the first long trip? The pipe will be sitting directly on it. Thanks
