Does anyone know where I can get a list giving bolt diameter and lengths of all bolts used on the 13b engine? Also does anyone know the bolt sizes (length and diameter) of the bolts used on the front and rear stationary gears for 2nd gen 13b? I think they are different lengths although the same diameter. Who, what or where is a good source for quality 13b bolts?

IMO I would not use anything else on engine parts. Except for stud kits that replace the tension bolts but other that that MAZDA Parts
