I pulled a rod bearing to inspect from a 1999 RT motor. The marking says "12 98 D, DA 49"

So how do I read this to determine what the bearing size is? Would Clevite 77's from Mancini be adequate replacement? I don't like the look of the bearing and thirty some dollars for a set are cheap insurance.


Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen! Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!

The lower portion of the shell is marked "12 98 C" No other markings. I don't have a mic large enough to measure the journal. I have never seen a bearing without a size on it.

They don't always say "std", I would push the rod up in the cylinder and mic it with something to verify std which it most likely is with that date.
