I recently bought what I thought was a STEAL on Ebay. A 1998 NEW never used Boxster hardtop for $800. Yes It was new and it looked like it belongs to a Porsche but when attempting to put it on my car (without the spinlocks installed) it became apparent that we are looking at a different hardtop. The lance/male attachments on the hardtop go right to the rear part of the softtop fabric. QUESTION: How can I determine what car this hardtop goes to? Where is the Part number inscribed. I suspect this top is to a 911.Please see attached photos. Thank You guys for your help.
