Again, I appreciate all the help and leads. I measured mine and they are in fact the same as Tim's. I checked with Rowe Truck Equipment here in Lafayette, IN today and gave them the Euclid numbers. They don't handle that brand but crossed it over to a Dayton 06-567 Lock washers - bent w/tab. Package of two, 2.50 I.D., 3.87 O.D., .06 height, and the application is listed as GM T150/T170. I do have a GM T150 axle. $7.10 for the pair and they will be here Wednesday. Maybe these additional numbers will help somebody out.
