Well Guys, I've exhausted my search capabilities. It looks like when it comes to headers there's now real swapping from one model or year to another model or year. You kinda can but not without real headaches like removing the headers to change your oil filter, and rubbing the frame.
The only way I've found to fit a different header is:
1. Buy aftermarket, they're not bad just expensive.
2. Make friends with a local exhaust shop who has a chop-saw & TIG-Welder.
