hey lads im needing some info on the numbers stamped on the bottom of conrods im currently rebuilding my 95 wrx engine as the cylinder3 conrod was slightly bent im ready to build it back up and got another conrod from another wrx open deck engine and have notice that my rods have 46 stamped on the bottom of them one with .46 the other has ..46 and the other 2 wer just 46 on them the problem is the once i have just got has a 45 stamped on the bottom what does this mean

 

Is a certain / any section of the rods 46mm and on the other 45mm ?

Sorry, just a shot in the dark.

 

surely the .. would be to pair the bottoms of the rods to the top?

 

Its usually the number confirming its a matching set.

 

as above, they are manufacturing/batch numbers..........
