cub cadet 129

That is a beautiful non-restored 129. Like the high back seat.

Looks like it may have had engine work? Engine's black instead of yellow.

Headlights only came standard on the 149 and 169 at that time - you can buy the set that bolts in place of the metal plate that is currently on yours now - but they are expensive I've seen em on eBay a couple times - you should also try checking with the site's sponsors.
