I've recently dealt with BB lifters. Pay attention to the "seat height" as that will affect your preload and you don't want too much or too little.

I have seen pics of the Mopar versions and they look like ONE version of the Sealed Power HT-976. I just put 16 of them in my engine -- but when I ordered them, 15 of them were 1 style and 1 of them was another. The 1 was the one that resembled the Mopar performance lifter-- the pushrod cup was completely smooth on the bottom. The other 15 had a small cutout there, not for oil to flow through though. See pic.



I had to order some more and finally got to 16 of what I needed.

All that was to say that they both had different seat heights, and some new Comp Cams lifters I have had an even different seat height.

The HT-976 might be worth a try for you - you can get them at O'Reily auto parts usually a 1 day order by calling the store, and they are cheap. If you need 1, order 4 or 5 and you might see the 2 different versions, you can choose the one closest to the seat height of your old lifters.
