I have a hurst comp shifter that came with a muncie i bought. I dont know what it fits. It has a number on the bottom front of 2083 and on the side it has a bunch of numbers 3216274 and 3306120. Can any one identify this complete shifter? We also have a 454 chev with a casting number of 3999289. It may be a marine engine. Any one know what it is? Thanks for your help on this great site.
