Any answer would be appreciated.

so you just needed to remove the two items. cull index removes the item at I in the list.
The following script takes a list of surfaces, finds the top and bottom and removes them.
0 removes the bottom and -1 removes the top. Then join the brep together at the end. (4.7 KB)
