What are the bolt sizes (length and dimension) for the front and rear stationary gear on the 13b engine? I think that they are different lengths. Also who, what or where is a good source for 13b bolts?

bolts are actually usually suprisingly reasonable from mazda, the front ones are a little longer because theres an extra plate they go thru

call Ray@Malloy Mazda 1-888-533-3400

some of the bolts are hardened i think so just buying the same size bolts but in different materials may present problems.
