[Secret Squirrel]

Jeffko,

Ditto on what BDRCobra suggested on mounting and expanding.
I used a different way to space my pipes from the frame than BDRCobra did. I heated and flattened the bend on the sidepipe mount and drilled a hole in the end of that and the frame bracket. I cut the rubber insulator strap from a universal exhaust pipe hanger for my spacers. Grade 8 bolts with crown lock nuts for mounting hardware. Drill & Tap frame. You may have to have someone help you pull the side pipes away from the body and use vice grips to clamp the assembly in place for measurement before drilling. Like BDRCobra said it is obvious once you get into it.
I have attached a pic of the parts laid out that I used. The round insulator on the left is what BDR supplied, did not use. I ended up using 2 rubber insulators per side to level my pipes. There are some other close-up shots of my pipes before and after install in my gallery.
Hope this helps.
