Roller Lifter Identification

I need some help to identify a set of roller lifters. They were in a 440 short block I just got and I disassembled the engine to freshen it up. When I was inspecting the lifters I found them in great shape and plan to reuse them but have one problem. One of the pushrod sockets came out of the lifter and is missing. I'm not sure if it was missing in the first place or it fell out when I was disassembling the engine and lost it. I would like to find out what they are so I can either get a replacement lifter or maybe just the pushrod socket. I think they are Mopar performance lifters but I'm not sure. They are needle bearing rollers. I have a few sets of old lifters, Crower and Comp but these don't match any of them.

The specs on the lifters are as follows; Body 0.903, Wheel 0.800, Pushrod seat height 1.500. The pushrod socket diameter is 0.697. See pictures below. Any help would be great.
