Convertible Top Replacement

[WillyT]

I need to replace the top on my 1997 Boxster. It had a plastic window which has cracked and faded. I have found a replacement top with glass window including frame in a salvage yard that was a replacement on a 1999 model. The salvaged one has a glass window. I have read some threads that indicate the glass window replacement will require modification of the top transmission for tight fitment. The salvage yard assures me all I need to do is take out three bolts on both sides, lift the old one off and bolt in the salvage frame and top with glass window. I had converted the old top to manual operation due to needing to do "the Boxster chop" anyway. Am thinking about trying to go back to automatic operation with the replacement top. The salvage yard is asking $1200. Any thoughts or advice from forum members with experience in doing this will be appreciated.
