The RS mounts are from the 964 RS and the 993 RS, it has been a commonly known upgrade to use these on later cars as they are not liquid filled.
Our RS mount kit includes the new longer bolts needed (not pictured on our our site). To be specific the kit includes the following shown in the diagram below:
2 x #12
2 x #10
2 x #14
4 x #15
4 x #13
4 x #16
4 x #9

Agreed. I ordered parts from Renn and I'll let you know how it goes. I really appreciate all the DIY information on here. I'll be replacing my Frunk switch, too, using help from this site.
I don't know how that compares to other dealers, but after looking at the online tutorials (Bruce's and Pelican's), this is obviously a job that almost anyone can tackle with basic hand tools and a floor jack.
Knowing that, there's no way I'd pay that much for the job, or the parts.

Thank you for your order!

21mm, the larger Y value, is a little over 0.82", just a tad under ⅞" but not likely enough to worry about since that hits the +/-1mm tolerance just fine.

Is that an accurate way to tell?
With my tips on a C2.2 the tips are adjustable. I could see how the original installer didn't line then up correctly and/or the single bolt holding the tips on allowed for some adjustment over time.
Now, if there is a measurement to actual exhaust pipe, that might be more accurate.

But to check it by the pipes alone: Due to the fact that the engine torque twists the engine mostly in one direction I think it is most common for the driver's side mount to sag more first. If you look at the pipes without the tips and see the left pipe is substantially lower, you can pretty much bet your driver's side mount has gotten weak. In my case, without the tips on, no measurement was needed. You could easily see that the left side pipe was hanging down lower. When I had to swivel the tips on that side at a noticeable upward angle to get rid of the excess gap I knew a replacement was needed.

Notes:
This is an easy DIY... actually easier than a brake job. It is just scary as you are screwing with the engine..... don't be afraid.
Regarding the sagging right side...... I am going to make an assumption (a swag).... if you have 75K or miles on your car, the right is sagging. This does not mean your mounts require replacement.... I am not sure they ever really require replacement unless they are leaking or clunking. But if you are looking for an excuse or something to feed your neurosis, let's say 75K miles will do it. Mounts are a wear item.

Just for amusement, and not to be alarmist, I did remember a long time ago seeing a post from some poor guy whose engine mount failed after having the previously owned car only two weeks!
After a bit of searching, there is the worst case outcome: https://rennlist.com/forums/997-foru...t-the-car.html
Here is one photo, he has others including how far the engine drops when this occurs. It isn't quite as catastrophic as I would have imagined, but not terribly pleasant either.
