82 with a Corbin

[whatscooking]

I have the seat off, it is a two up matching color seat, that has a place to insert a backrest pad shaft but underneath where I think there should be a bracket of some sort there are six bolts with nuts in the place where I bet a bracket goes to hold the shaft.. Is there a piece I am missing.

On an older one that i had it was just a metal sleeve that the backrest slid into.
Looked similar to this. http://corbin.com/accessories/backrest_inst.jpg

I suppose someone has removed this sleeve from this seat, guess a call to Corbin Monday.
