Meritor (who owns Rockwell) still has the parts book published on their site
https://graphicvillage.org/meritor/pb90172.pdf

Seal dimensions are included as well as the Meritor part number, for instance rear output seal is A-1805-E-447, 2.5" OD, 1.75" ID, .77" wide. If the seal number isn't legible on your current/old seals this maybe the best way to find the correct seals. You may even be able to cross reference that Meritor number to a Timken (National) or SKF (CR) seal number. Using the SKF seal cross reference site, http://www2.chicago-rawhide.com/popu...kup_457012.htm , the seal above (entered as a1805e447) crossed to a SKF 17387. I was able to find the correct seals for my Rockwell T-32 and purchased them off EBay from Locate Ball Bearings.
