Kooks like i am going to have to cut out bolt that goes into frame on my
leaf spring, Can't seem to fing size listed any where. Any help would be greatful.

 

You wont be able to get the exact replacement unless you pay $8 per bolt at the dealer. Try to save one of the 4 and take it to a good hardware supplier. If i didnt just clean out my garage I would have the package of what I used

 

I had to cut one of these and just got one at the dealer. It comes with some locktite in the threads. I think it cost me 9 bucks after tax, which really isn't too bad for the assurance of knowing it is the right part
