69 Chevelle\Cutlass parts interechange

[csouth]

I know a decent amount about 70-72 part interchange, but I'm a little stumped on 68-69. I know some of those parts are "year only". What I'm asking specificly is the do the internal door parts from a 69 Chevelle and 69 Cutlass interchange? When I say internal I'm referring to everything between the inner and outer doorskin. I see that the regulators and glass have the same part numbers for both models which would leave me to believe so. I'm spending someone elses money so I really want to be sure. Anyone with knowledge in this area would be appreciated.

Thanks
