Gosh I cannot believe how some people will not change bolts. These are just like rubber bands. The only difference is that they strech very slowly and not very far. Problem with old bolts is once they stretch several times they loose their ability to exert clamping force on the parts being held together. Now these are pretty much Great to Look at also. Once Floyd whips up on pops he can rub it in a little by telling him his car goes so fast because the shiny bolts have less drag.
