Back in the 60,s to 80,s,it was the rage to convert coupes & sport coupes to rumble seats.I did the same Thing back in 83 when we went on a 1,000 + mile trip & there wasnt enough room for our 10 year old daughter in the car.It gave us lots of room & our daughter loved being in the rumble.These days there are many who are converting the other way as a trunk is much more practical.I was glad when I restored my late 30 coupe that it had the trunk.Much easier to load things in a trunk and it will hold a lot more than a rumble.Much harder to lift suit cases etc over the open R-lid than into a trunk lid. But,hey,its your car-do what you want.
