You get 4 x Upper Poly Bushes, 4 x Upper Plastic inserts, 4 x Lower Poly Bushes, 4 x Lower plastic inserts and also 4 x new lower washers in a kit. You need to reuse the steel centre out of your original upper bush.
This is an assembled lower with poly, plastic and washer:

The washers that come with them now will be machined billet aluminium rather than the welded steel ones there.
Lowers fitted to a subframe:

You can actually fit them without removing the subframe completely - you can lower it on a jack on the car enough to get the old bushes out and the new in, even for the uppers.

I've also got two engine mounts, one 65mm to fit the V6, like this:

And also one 70mm to fit most XU engines, they're both 95A shore, but they have a solid centre and a honeycombed outer, so that they're stiff radially but almost as soft as an OE bush for warp modes - the V6 one feels almost like an OE engine mount in terms of lack of vibration, even on a cold idle. Centre tubes again are machined billet ally.

I can do custom stiffness engine mounts if you have a specific application in mind, track cars, etc - but there'd be a lead time of about 3 weeks on custom ones.
