Hi all just dropped a 401 nailhead with st400 (less Yoke) into a 62 lesabre the tag says b SUPER TURBINE 400 R so the original non running 401 & dyna flow where yanked . so here is my question will the yoke from the danya flow work on the st400 i'm guessing no. So I need a yoke to fit the st400 will any other yoke work ie tubro 400 etc thanks in advance for any help cheers Will
