Where does the rear cab support go

[fijman]

Alright if got most everything mocked up for the rocker panels. But where does the rear cab support go. I don't see any remenants from where the original one was. The front one at least had some I can connect to. I know it's supposed to match up with the seat bolts but..... I don't have stock seats so the bolt holes could be one of the random holes in the floor pan. The front connected through the body mount. The rear body mount looks too far back. I looked through some threads. One had a picture but the thread didn't show it. Thanks for the help.
