Rear bottom quarter replacement

[Pahs59]

Just interested to know how anyone on here have gone about with the replacement of the bottom rear quarter section..I’m in the process of doing it now and in two minds about what to start on first ...I’m replacing the section from the quarter to the chassis as well..any suggestions plus photos would be a help,I realise it’s a matter of whatever I feel comfortable about the way I go but maybe someone has the best way to attack it.thanking all in advance
Cheers
