Rear quarter rust repair

[fe350chev]

Hi

Just wanted opinions. If I have a rear qtr panel on a sedan that needs a replacement section below the ridge and the back lower box inner section is rusted completely, then my instinct is to go crazy and cut it all out, without drilling/teking the old spots out and just custom make a new section myself. BUT, is there any merit in trying to replicate the whole original thing by plug welding as like a floor or should I do it the way I want. Ill do both sides. This is a car that has new floor and sills and they arent NOS. Any thought would be appreciated as I dont think it matters as the original construction looks to be very average quality  :(

Yeah I'm with you ,I would make cardboard patterns as I cut it all out then replace it all. I'm totally self taught and mostly use a mig and it prefers clean steal and find myself sometimes cutting body away just to get to the area that needs replacing. Good luck.

Yeah thanks. my sentiments. the back is all rooted anyway. maybe i could incorporate a custom exhaust outlet. might look gay though.
