Anyone have a 'clean' solution for using the factory belts with aftermarket seats by using a belt guide?

The Corbeau LG1 does not have a belt guide, other than for a harness. With the
factory upper belt mounting location, the belt cuts right across my neck. Just wondering what others have done.

I know I can buy shoulder pads and/or belt adjusters, but I like the idea of possibly routing the belt through a guide, if possible.

 

just get harnesses and route them through the seat, with the strap mounted to the rear seat belt location on top, that's what I did with mine

 

you can see the way it's routed here
