Curly:
I successfully located a 2003 top for my 2002 Boxster by checking listings here:
Car-Part.com--Used Auto Parts Market
According to a couple of threads posted on this forum a 2003 or 2004 top is a bolt on project. After finding a Meripol Blue top at the above site I reviewed those threads (thanks Boxsta Boy and others for the articles and photos) and the 2003 top I purchased from one of the junk yards (may I still call them that?) in fact bolted right on to my 2002 last Saturday. Although it is a two "man" job I found that my wife was an exemplary assistant. Assistance is needed only to hold the thing in place while getting the bolts started.
There are presently listings at car-part from about $850 to around $2400 for 2003/2004 tops with the glass window.
May I again thank the members of THIS forum - I now have a glass rear window thanks to the shared knowledge. I am most grateful.
