Vespa floor runners for project

Am thinking of restarting a project I abandoned a few years ago.
The legshields have had like the short rounded back edge runner boards welded to them.
Wanted to know which are the best Vespa floor runners to use, the ones with the outer runners which have a curved edge.
Am looking for a weld on bump stop for a Spanish SX200 engine case if anyone can help.
Thanks.
