(limit on number of words in a post, so here's the rest)

. First take a look at the spacing under the front of the clamshell on the left and on the right side (i.e., in between the underside of the clamshell and the top surface of the front section of the convertible top).

If that doesn't yield any clues, disconnect the clamshell so that it is not being driven by the V-levers and stow the clamshell in the 45 degree position. Then operate the top with the switch to bring it all the way down. When it stops, take measurements so see how far below the top edge of the rear quarter panel each side of the stowed convertible top sits. Both sides should be even. It they are not even, check to make sure that all the connecting points at the joints of the mechanism are sound and have no play in them.

Let me know how you make out.

Regards, Maurice.

Mike:
You have to try to "balance" the spacing to achieve the best possible result with the top up and the top down. Raise the clamshell (using the switch) until it's about 3 inches above the front edge of the rear trunk. Then disconnect the cable at the psgr side of the electric motor and use a cordless drill to drive the psgr side transmission. You'll see the V-lever start to rotate as the psgr side of the clamshell starts to go down. Only go down about 1/8th of an inch and reconnect everything and run the top through a couple of cycles to see if you got any improvement.

As I said, it's a bit of trial and error to get the best balance.

If you can't get any improvement, you have to check to make sure that there is nothing impeding the complete stowing of the top on driver's side.

Maurice,
I have a Boxster and I have aligned my clamshell perfectly when the top is up using your posts...thank you. My issue presently is that the driver's side rear (closest to the trunk) of the clamshell sits about 1/4 inch up from the passenger side only when the top is down. Thoughts?
