Just thought I'd post a link or two here about seat modifications.
Here's one that I think is pretty simply and elegant.
Seat Modification on the CT90-CT110.COM web site
And another one that I look at being structurely strong (if not overbuilt).
My Florida CT friend, John Kelly, knows the guy that owns Specific Design, Inc.. John sent me the following link about this guys CT Seat Modifications. I got his email address, sent him an email about using his seat modification info on the CT90-CT110.COM web site, but never got a reply back from him.
