I would call it the stoneguard locking pin, but that's probably not quite right either. May be worthwhile advertising on the sister site, classic vans. Would be more in the post 70's era

As a last resort you could remove the old ones and rivet them back onto the new slides you bought, I would give them a bit of a clean up first though
