I had the manual one when I had my hard top...gave it to the guy who bought my hard top.
It worked great.
It is a standard come-along (came in the original box)...the t-setup was stock square tubing that the welded. It also uses off the shelf hooks with rubber protection.
The nice thing about it was that the center support for the t-portion was a larger tube with welded on eye socket....it let you place the connection so the top was balanced when it was pulled off.
