Redoing the Suburban headliner(how?)

[zeusflash]

The restoration of my wifes 72 Suburban is nearly complete. One of the major hurdles left is the headliner. We have tried to maintain as much originality as possible(never mind the 402 and 700R4!). We would like to reproduce the original headliner as closely as possible. We have all the bows and need only one of the plastic retainers that hold the headliner sections up(broke in 2 places during removal). Has anyone done this? Any advice or suggestions? Any help would be greatly appreciated!
