So I picked up a M98 from a 2005 IS300 and seems the carrier bolts don't fit the same as a 2003. I left the bolts at the junkyard cause figured they would be the same. Maybe they are mounted different or am I missing something
Different part number is from manufacturer changed suppliers. Same parts. One made in one plant. The other from another. I have swapped hundreds over the years. From IS to IS, from FRS and BRZ. They all interchange. The FRS and BRZ just need a bushing mod or swap. So if it is from an IS300 from 2001 to 2005 and going in the same years. They are exactly the same.
