L-4 Windshield Channel and Installation

[me109me109]

Anyone have a good source for the rubber channel at the base of L-4 windscreen? Furthermore, did any L-4s use the cub style metal channel for the front windshield? Does anyone have the blueprint/decent photo(s) of the tabs riveted to the boot cowling that holds the base of the windscreen down?
Thanks!
