If it's a 428 CJ or SCJ the only possibility is a PGB-AF or one of the variants -AF1, -AF2 etc. All of them came with a cast iron tail shaft, R servo and extra severe duty clutch pack and the special valve body.
Particularly as years went by the big retail transmission shops would not have the proper rebuild kits to rebuild a real CJ transmission so inevitably they would substitute things to get by. No telling what you have until you know. Pull the servo cover and take a picture, it will tell you if the case has been swapped.
The "D" servo was third from largest, it was typically found behind 390-2V applications. Not a good sign for you.
That is my concern, the transmission is still in the vehicle and need to at least drop it to see if the vin is on the transmission. All the other numbers seem to fall in line but as Bob has stated in previous topics if the transmission has ever been rebuilt they could have just thrown another case in it off the shelf rather than rebuild the correct one... BTW the tag is mussing also at the servo and that s what made me start looking. I just didn't know if there were different situations that used a different servo. My car is a 3.00 open differential and A/C so doesn't have a lot of get up and go.
