Is a 69 Charger rear seat different than other 2 door B-bodies 68-70? I'm not talking about the covers and the pattern but more the frames and the foam. I think the backs are all the same, I know the bottom of a 4 door is different but and for some reason I think the Charger bottom is different too. So who knows the truth?

Thanks in advance, Kevin

Same-to further expand they all use the same rear floor pan part # 2900801. This applies to 2 door sedan, hardtop, convert and yes even 4 doors just not wagons. it's in section 23-32-24 of the parts manual if you wanna check it out,

Thank you. The 4 door rear seat base is different though correct?

Bring yours by to compare, I have a set out of one of my 4-doors right now.

It would be cool to note the differences.

I'll see if I can get it in the overhead next time I fly up. I actually have a rear seat out of a four door in a 68 RR but it's tucked in a back corner, I think it's something about the corner being rounder on a 4 door since you get in from the side instead of straight on from entering the front doors.

You are correct you need to stick with the standard two door seat

4-door bottoms have a rounder shape at the outer corners to ease ingress/egress.
Charger rear seat bottom & top (properly termed cushion & back) are same as 2-door Belvedere & Coronet lines, I've seen them interchanged.

Thanks folks.
