I have been working on installing a Ruckstell rear end in Sambuca for quite some time now and could not get it to shift, so I brought it with me when I went to visit my good friend Dick Welch. Dick immediately knew what the problem was and set to work on it right away. Placing it in his shop vise, with the help of Marvel Mystery Oil, he began to move the working parts. Soon Dick had it working as good as new. Thanks to Dick Welch and Marvel Mystery Oil I can now drive and shift Sambuca.
