Rod Bearings

I just bought some new rod bearings for the a6 at O-Reilly's (got them for like 23 bucks after tax, alot better than the 48 bucks Autozone.com said they would cost,i still don't know why there is such a difference) and i took them out but i'm confused, they are all the same size. When I took the old ones out they looked like they were two different sizes. so are the ones i bought right (they came 8 in a pack) or do i need to buy additional ones?

man they come in like 8 different sizes... there are actually markings stamped on the rods and crank as to what bearings you need....

check out the manual...

rod bearings are all the same size. you can get them thicker if you have had your turned down a few thousandthe other than that they should be the same width
