Anybody know if the 240K Sedan and Coupe rear bumbers are the same/interchangeable.

Yes, they are.

..........but don't blame me if it doesn't fit!

(Parts numbers are the same)

ummmmmmmmmmm

looks like, unfortunatelty I didn't try.

but I think the same

Sure are - at least on the '73's!

(our hardtop now has a much straighter sedan bar)

edit :

not sure about the mounts as I used the originals on the car
