i have a 69 hardtop with rear deforst. is this a rare option ? and can i order a new rear package tray for the car with this option ? also when i turn on my wipers i hear a loud clunking noise near the wiper motor. could this be caused by something being not lined up right in the linkage or maybe the motor going bad ? any help on these questions would be appresiated. thanks..

You'll have to cut the package tray for the blower. The clunk could be many things. You need to take the cowl off and see what's loose.
