thanks roger and oops. i already have the pull scale and the 12'' caliper its that alignment tool that i need. the last time i set up my knuckles i didnt shim them correctly and now that im upgrading to 30 spline longs,im rebuiding the knuckles by the book. hopefully i get no more leaky leaky. oh and yes i got marlins seals, a major difference in size and quality from what i can tell.
