Were the '68-'69 Rivieras available with manual window regulators or are there ones from another car that work?
Manual or 'crank' windows were available for all years of Riviera - power windows were an extra cost 'option'. Pretty sure they were also used in other GM models, but don't know specific matches. :TU:
Thanks for the reply! That confirms my suspicions. Now to find all four manual window regulators and door panels.
