Those looking to secure cargo and/or wheelchairs etc this site offers a lot. While the L Track products aren't new this outfit has parts to make something strictly utilitarian into something more eye-appealing for vans with higher level trim packages. DIY builders would find the track flange selections quite easy to integrate into plywood floors over the typical van metal floors.

The wheelchair docks and seat belts are all agency approved which should mean the quality is quite high.

Anyway hope this site would be useful here.
