LMC 3 Point Seat Belts in 69

[rmr_69c10]

Anyone here have any pictures of how they mounted the LMC belts (retractor section) of their 3 point belts to the factory mounts? In my opinion there's no way they are a direct bolt in installation. It also seems the retractor mount on the driver's side doesn't fit very well with the gas tank. If no one here has any great thoughts, these may get sent back. These look like they would work better but are more expensive: http://www.seatbeltsplus.com/product/CHT6872-Bench.html

Thanks!
