hi men, if you follow this forum you may recall one of the differential bolts backed out of my 416-8 tranny last winter. extensive damage resulted. i recently crated that tranny and a spare and shipped them to racinfool40/mike. i used fastenal for shipping. round trip shipping from mass. to ohio and back was $125. mike just called me and said both are totally rebuilt. i really appreciate mike doing this! his prices were reasonable. he really knows his unidrives! i would encourage anyone who needs unidrive rebuilding to contact mike. best regards mike in mass.
