If you are interested in saving some money on this project yet still retaining a decent amount of stiffness in the bushings, you can use old/new hockey pucks. What you do is drill out the centers of each puck for the bolt holes. For the GNX bushing (which i believe is in the rear fenderwell) you need to use two pucks for each. there is no bolt for this bushing, the bottom puck has to be reduced in diameter and height and if you drill a larger diameter "half hole" in the top one, (not all the way thru it of course) you can make the top portion sit over the bottom one. If you can picture it, it will look like an upside down 2 tier cake. the bottom portion sits in the frame. And I believe we bolted the two halves of the GNX bushing together as well. I do not know the exact dimention of the GNX bushing. As far as how do you install them, you can use a 2x4 on top of a jack to raise the body off the frame once you have all the old bolts loosened.
If this sounds fishy to you i can understand, but I have 14 hockey pucks installed on my car and i remember it stiffening up the car quite a bit after it was done.
Mark Martone is man who gets all the credit for the project. And the hardest part of the project was finding enough hockey pucks to do it....I ended up finding a buddy up north (i live in fl) who went to a play it again sports and bought em for less than 2 bucks a puck.
