Dave Barton has excellent wiring diagrams on his site. I used them to build the harness for my MS.
The rest of the stuff you can just use stock throttle cable and fuel line. And IC tubing you can use 740/940 + universal stuff from ebay/amazon/summit. Just cut and clamp what you need.
It needs some clean up but I scanned a wagon handle cover. The software is rough to use and has a hard time aligning thin objects. You can make out what I scanned but it seems like it's far off from making something printable.
Pull handles like the ones on the headliner?
I think I have a few of those other parts as spares. I might try to grab a few to take back and scan some more. It's a bit of a learning curve using the scanner. Hopefully I can get it working a little better and more efficient and I can get some...
