Recently I discovered that the pitman shaft seal on my steering gear is leaking. I now have to add power steering fluid every few times that I drive it. I picked up a steering gear pitman shaft seal kit from Oriely (#8717) along with other stuff that I needed. If I enter my car information on other sites like Rockauto I find kits that look the same. I got the pitman arm off with a pitman arm puller from Autozone after first trying to use my cheap 3 jaw puller and snapping its bolts. Then I cleaned a few gobs of grease and other grime from around the pitman shaft only to find that there isn't a snap ring there. The visible side of the seal(s) is rubber around the shaft, metal in the center (perhaps with a very thin rubber coating) and rubber on the outer part where it fits into the steering gear casing where it seems to be held in by a lip. It doesn't look like there's a spot for a snap ring. It doesn't look like any of the ones in my kit. I'd prefer to replace the seals myself as opposed to getting a remanufactured steering gear but I don't think the ones I bought will work. Attached is a picture of the pitman shaft seal area of the steering gear.

I can't seem to find any drawings or pictures online that match the seal that I see without a snap ring (aka retainer). I've seen pictures/videos/drawings showing a steering gear with the kind of seals I was expecting to find that otherwise looks nearly identical to what I have. Google has lead me to this forum a few times in the past with helpful information but obviously no luck this time.

What seal kits would be compatible with my steering gear?
If I got a remanufactured steering gear like one of the ones that show up for my vehicle on Rockauto would I have any compatibility (or other) issues?
