What are the differences between a LWB 69-73 rear quarter panels, and the 74-77 rear qtr panels? My project had rear metal flares added by the PO and I want to return to stock. There seems to be more used 74-77 qtr panels available than the LWB ones, but I don't know if they are interchangeable.

Is it easier to replace the entire qtr panel or just cutoff the flares and weld in the correct arches?

Thanks in advance.

Happy New Year!
