Default 1992 A/C system flush or not

On my 92 the compressor seized up. Always running even with no pressure. I put another compressor in from a clean low mile car I found in the wrecking yard that got hit real hard. Evacuated system and it holds -30 for 30+ minutes. I just changed the orifice tube before charging and it has metal shavings. So, do I need to pull the whole thing apart and flush it? I probably need a new dryer too. Any tips on flushing it? Do I need to remove the evaporator and condenser or can I do it by removing a couple hoses?

Personally I would remove everything and backflush each individual piece. For sure, remove all lines from the compressor first so you don't get shavings in it.
