Help with Axle Housing Identification

Yup truck axle. The 61-71 Sweptline has pads on top at 43 inch's. That length sounds about right. Make sure it isn't a 57-64 tapered axle housing. Its been a few years snice I worked on one but, it seems to me the seal was different. I have a 64 tapered and 68 in my shop. From my research you can't use an early housing with flanged axles.
