Do any parts on a '69 coupe swap to a '67?
i.e. replace '67 front drums with dics from '69?
Steering column?
Engine?
Other?
Anyone with experince or links, please let me know.
Yes, but is it a 250ci car? Those had the V8 suspension and rear end and IIRC it was the only way you could get discs on an I6 car then Everything you listed will swap, anyway.
