Steering Box Removal

I am Looking for advice from those who have removed their steering box before from a 71 Dart Swinger or similar A body. The details are as follows.

1. 360 with Hedman headers
2. Manual steering box

I’m no stranger to taking things apart I just don’t want to go overboard with the disassembly which happens sometimes when I get into unchartered territory. Also should I try pulling the Pitman arm while the steering box is still in the car or wait until it’s out? Any recommendation on a puller that won’t break the bank? Thanks
