I met Lwin tonight and together we wiggled the seat release and we experienced the problem I described earlier. Lwin got out his SVX manual and we decided to take apart the back of the driver's seat. Turns out that there are two releases, one on each side of the seat at the bottom, controlled by the single handle on the left side of the driver's seat. In my case, the right release was binding and would stick. Unfortunately, we will need to take the whole seat apart to get at that release in order to free it up. So, that will be a project for another day.
Anyway, I want to publically thank Lwin for his time and effort to help me on this. This is not the first time we got together on SVX business. He is known to be a great help to everyone who asks and especially those of us who live in the area. Great guy!
Thanks, buddy.
