Julian,
I did not have the safari top so can't speak to weather they are the same as a regular top. The very front bow is smaller than the rear two. The tabs that connect the bows to the top are different for the back two. It's been a while since I took these out. I'll dig mine out it might refresh my memory, hate to guess and potentially send you down the wrong road.
