Where to find connecting rod bearings

You can try Summit Racing I did a quicj search and came up with some choices. I would check them out, and even call their customer service and ask if the ones you pick are 1 inch wide. here is a link, but you can cruise the site yourself also. I did enter in the Make and engine for the search, I dont think entering the year and car worked very well, but if you enter Dodge , inline 6 and 225, into the search pane, you will find parts listings. hope this works, and if not you can try JEGS also.
