What is the part number for the exhaust gaskets? Also, are the spring loaded bolts used on the axle back portion?

 

Please elaborate your 2nd question

 

I have two different bolts. The aftermarket bolts that are on it currently do not have a spring around it. In the box with my original mufflers had a set of bolts that had a spring around them. I was looking at the parts diagram and it was showing some type of spring around the bolts used around the axle back area.

 

Also, what do the original gaskets look like (are they complete circle or do they also have 2 bolts)? I am not able to find any at the auto stores.

 

The spring loaded bolts are OEM. My Joe-Z axle back used "aftermarket" bolts, too and they were not spring loaded.
