also...top will go down differently , depending on material in top...heavier top material bunches up more....is it plasic rear window? or glass , the ones w glass tend to not fold as much also...my 69 top went down so far and even people didnt even think I had one (I picked the thinnest top material I could get)...friends` stuck up 2 inches to 5 -6 inches dep on car , top material and rear windows
