Gary, That is funny that you mentioned that...I thought that they had shorted me the header gaskets ,but I tore apart the box that the headers were in and I found them( they were in a envelope taped to one of the cardboard sections. I was also missing 2 clamps and the bolts. You need to buy (6) 3/8x1 1/2" bolts.
Also, cut the heatshield on the pass side to allow room for the O2 sensor. That part was a nightmare. Also, disconnect the wiring for the starter and move the harness out of the way.
You also have to take the oil dipstick completly out.
Don't forget to have a cold case of beer and a package of band-aids for you knuckes and wrist. You may want to keep the garage doors closed as well. I was cussing up a storm and throwing wrenches all day long!! Hope this helps, Call me if you need any help. -Neil (roger has my number)
