If your talking about the ketal part thats attached to the body its not to bad. You need to drill out the rivets for the existing mount, clean the area and fix any cracks and then reattach the new mount useing SS bolts, nuts and washers. It is also a good idea to fill the mount with Urethane foam to keep water out and seal the thing up forever.

it works and is fairly easy to do if you are alone, not trying to get a rivit gun in position and/or balance all that crap....

I did mine with stainless screws/nuts/washers, polyurethane adhesive, and new capture nuts. It's a subject that's been covered many times. http://forums.corvetteforum.com/show....php?t=1603168

As Sixfooter and Batman mentioned, I would fill up the inside of the new metal body mount with some type of conforming substance before riveting or bolting it in. The fiberglass **** that the metal support fits over can get brittle and worn with age. And putting all the body forces on a few rivets or small bolts can be scary.
I used vette bonding adhesive in the metal support to get a firm seat between the fiberglass and the support.
Also, you can get shorter riveting attachments for you air impact gun that will fit in most places. Use reduced air pressure on the gun. There are some old posts outlining the procedure.

I put the thicker one on top too, that was closer to the original height of the old mount(and that was collapsed some too). some kind of instructions with those kits would have been nice though. SS machine screws are the way to go instead of rivets unless you're a die hard NCRS guy.

I only did the #4 mounts because they were in pretty bad shape, and when I actually got into them it was even scarier how bad the frame mounts were. From what I could tell though they go in the same orientation, only the wider disk is between the frame and body, and the tapered one is between the bolt head and body. I thought the #1's were like the #4's because the bolt comes from underneath, but don't take my word on that. I can't picture them off the top of my head.

I did check out the rest of the mounts and they are in pretty good shape still with minimal surface rust, so I left them for now. I didn't want to get into a body off resto just yet. too much down time over the summer for that.
