Part numbers are 92068147 and 92068149. They used to be about $120 a pair but the original supplier went out of business and when the new supplier eventually released them the price more than doubled!
They do go straight on but technically require some studs/retainers which are ridiculously expensive at about $4 each (92066971) but you can improvise with just normal bolts with a bit of modification. Assuming your L76, like mine, has the extra vanity/beauty??? cover on the inlet you'll have to remove that or the covers won't sit properly.
