MSA replacement seat belts

Can someone post detailed pictures of the MSA seat belts installed in a similar fashion for what I need to do in my '73? The directions are unclear as to what bolts go where, where and how to use the nylon spacer, the orientation of the "L bracket".... and I am not liking what I am finding as I try to figure out the proper orientation for the shoulder mount point - what appears to be the proper orientation (judging from the pictures on the MSA web site) results in the belt being slightly twisted and not pulling out and retracting easily.

Right now its Sunday night, and I want to decide in the next 24 hours if I'm sending these things back or not...

Thanks!
