a 14" long 3/4" threaded rod, i welded the nut so i can put it in the vise, i used a piece of nylon i had and drilled a 3/4"hole in it. use the top nut to compress the spring.....worked slick for me
i tried to attach a picture of the tool i made but it wouldnt go through so if anyone is interested in making the tool email me and i`ll send you the picture of it......mike800z@aol.com
