I replaced my asbestos heatshield last December, with a NOS asbestos one. It was a breeze to remove, but one of the 4 bolts used to attach the new one back onto it's bracket was next to impossible to thread. I gave up, and the shield is now holding on by only 3 bolts. It hasn't seemed to be a problem yet... but if anyone has any helpful hints, short of removing the engine :-) would be appreciated! Jeff Angwin VIN 3034
