36 in sleeper for 1978 359

Got a line on a 36in sleeper for my 359 daycab. My 359 had a 36in sleeper according to the build listing but it was removed by a prior owner.

Looking at how these sleepers were mounted to the frame. There are some brackets in the area but not sure how they were used. There are 2 strange brackets that mount on the outside of the frame, one that they mounted air horns on. There are 2 more that have a large bolt thru them and appear to be upside down within the frame.

Can anyone who has a 36in sleeper on a late 70's to early 80's 359 give me a few pics one the underside of the sleeper?
