I am unable to get all of the upper unit oil seal pieces out. the top dish, spring and rubber came out, but the bottom retainer dish will not move. Anyone have experience with this nuisance?

bottom dish retainer??- do you mean the outer bearing race above the seal? I had to use a slide hammer and heating the housing helps as aluminum will expand with some moderate heat

keep track of any shims carefully
 
Great suggestion. Do you happen to remember which slide hammer you used?
For this unit the seal is a double lip single seal. I think its the upper most casing that is stuck.

its a 5 lb hammer had to grind the jaws down a bit to fit under the race. any HF will have the hammer

Heating the housing will also help. The aluminum will heat up faster. Not sure if you can use a drift from below. obviously easier if you are replacing the bearing and race .

All this is well laid out in manual 14

FYI I was looking back and noticed I typed wrong HP. I know it doesn't matter but it's 5.0 260hp.

Typically it would be the 5.7 (350 CI) that is 260 HP as seen posted here.

The 5.0 liter (305 CI) ranges in years and in HP from 200 HP to 260 HP. But the 260 HP versions are rare. Typically it is 230 HP. But without a serial number in is UNKNOWN. Most seen here are typically 200 HP to 230 HP.

The 5.7 Liter (350 CI) typically ranges from 230 HP up to 320 HP based on configuration. Most seen here are 260 HP Standard - 270/280 HP MAG.

Note: Any engine HP and Torque rating/limit is base on OUTDRIVE used.
Alpha drives typically have a limit of 300 HP and Heavy duty gear set allow higher such as the 320 HP 5.7 Liters.
The torque associated with a SBC related to its HP is the Key and the overall determining factor.

back in the '80's they used 454/Alpha combos and the upper gear cases failed miserably. Thus the introduction of the Bravo late '80's (1988/89)

BBC 454, 496, 502 etc (NON High Performance).............Use the Bravo drive which can handle much greater loads (HP & Torque)
