On my 1971 Challenger convertible there are 2 rear seat catches per side, one right in front of the other. Why are there 2?

My wife's 71 chally vert has the same???

I've seen the same thing on all the E-body convertibles I've worked on.
I think that back floor pan was preassembled with the hardtop seat catch location. When used on a convertible, the second catch was added in the correct spot.
If you look at the total production of hardtops vs. convertibles, it probably wasn't worth messing with a second pan.

That makes sense. Thanks.

My 1970 is the same way.

our 70 chally vert had two on the pass side. original floors in the car. I ended up removing the additional one on the pass side due to some interference with getting the seat bottom to stay down correctly.
