Pulling 522 stroker from 1970 Swinger Help please

Hello, ready to pull big block from my 1970 Swinger( broken timing chain) question, do I remove trans, bellhousing while still in the car or do I pull it out with the trans attached? Also header clearance, no way to remove headers while motor still in position, any suggestions? Pull it up a bit and then remove? Steering crossover rod under oil pan, do I need to remove it? Thanks for any info, Bernie 1FC0FC15-97FC-4DC2-9DC6-9B7EA556C1F1.jpeg1FC0FC15-97FC-4DC2-9DC6-9B7EA556C1F1.jpeg
