Looking for a 737-300/400 series slide platform, PN 65B67440-3 (or -5) which is the complete assy with hardward.  The platform minus the hardware is PN 65B67437-1 which I can also use. If anyone out there is doing a teardown please let me know if you have this. Alternatively, if you know where I can get one, or if you have one to sell, please
