you can buld a diesel willys wrangler on the website so I would suspect you should be able to do the same if they do a gladiator willys. No leather in the wrangler willys. I am not a fan of the body color fenders, which is not an option on the wrangler willys. l really like the grill and the rims/tires tires. I may just do that to mine and Call it good.
