Manfrotto 3021 Pro Tripod Columb

Im looking for a center columb for this tripod, hopefully used to keep costs down. This tripod does not have a round columb, but has 3 flat sides with rounded edges on the rest of it. What center columbs from what tripods can I use for the 3021 Pro? There is a columb under part number: Manfrotto Compact Advanced - MKCOMPACTADV-BK for sale. Will this work? Or what about this part: Manfrotto R1035,21L1 used on the BeFree units?

Here's a link to Manfrotto parts.

I may actually have one...I'm travelling but will check when I'm home.

Well, I'm back home and found the spare tripod center column. I have a Bogen/Manfrotto 3021 tripod and I have a spare center column....
However the spare center column that I have is not for Bogen/Manfrotto but rather, it is for a Berlebach.
Sorry.
