GT40 all the things!
I picked these up from Energy Suspension instead of cfm. They have a lip around both inserts so you dont have to glue them in like the how to says, but the inserts were not only a pain to get in, but it took a lot of finagling to get the mount back in also. Since they have a lip its wider and didnt want to fit, but I think it will make it a lot stiffer. I'll update after i go for a drive. Here are some pics:
