I need the specs of some nuts and bolts for my radiator, downpipe, exhuast, driveshaft, diff casing, and diff mounts, axels...and ummm...I think thats it. Need the length thread pitch and all that. And im pretty sure I may need to go to Mazda for the driveshaft washers/spacers becuase they are weighted. thank guys.
