I've got a 73 electra 4 door Most of interior was beat up except headliner , dash , seat belts, some door panels and steering column The metal panels under dash need repainting They are dark blue Seats were trashed so I got another seat front and rear real nice shape but it's a dark red from a 76 olds 96 My problem is 73 and 76 have diff mounting points on roof for front belts I don't have any red c pillar material Headliner from olds has the big could out for the top of seat belts I don't have any carpet as both were trashed Dash and all interior parts would need to be painted red from current blue My steering wheel is blue My dash is blue The door panels are diffent style but need some work If I use the red interior I'd need to have it recovered I'm stuck on what to do Factory interior is blue and was bench In going 40/60 Either route is going to suck and require funds
Sounds like what you have to work with is about the same as that Lesabre I have. Found and purchased the factory correct material from SMS and had the seats recovered. Got a carpet kit from ACC and had my local shop recover the headliner. Got some color matched paint and freshened up the plastics. Probably got around 3K into it and 8 hours of my time.
