Clueless parts guy. There are no R or R-style vents and no newer or older vents. Both variants were available from day one for all RWD F-Types. In a way these are the original hood vents - the CX-16 concept had hood vents like that. These are just black pack RWD vents.

Non black-pack RWD cars with the standard chrome trim for some weird reason came with the much worse open mesh vents. Never understood why.

 

That's weird Valerie, I don't find Harper's shipping expensive. It must be the distance. I have always hated the honeycomb vents, but it wasn't until I saw this post and thought, ok, now is the time to do it. It's funny though, Harper emailed me and said the part doesn't fit my VIN, The graphic at the bottom showed it would. I think it wasn't until they moved the vents closer to the front of the vehicle, was it the AWD cars, that they changed the hood. I ordered them, they just arrived. Shipping for me was $16.69. It sounds silly but if there is something you want and shipping is stupid, ship it to me, I'll put it in a flat rate box and ship it, it could cut the the vents, for example to $32 shipping. Just a thought. Here is proof positive they fit, 5-10 minute replacement time. Thanks to the thread starter for motivating me..

 

Same here I replaced those waffle style vent covers, see my post number 12 above.
