WTB:GM Bubble top or full sized GM convertible

[Hdesign]

Had to sell the Camaro, couldn't fit 3 kids in car seats in the back. Looking for for a straight and solid driver under $15K to haul the fam around in comfort. Ideally I'm looking something rust free and turn key but if I can get something that needs some work for a great price I'll consider it. Willing to travel a bit or have it shipped if the price is right also.

Here's my list if you have any leads: 61 Olds/Buick/Pontiac bubble top, 67-68 Wildcat conv, 67 Grand Prix conv, 65 impala conv, 67-68 Lesabre conv, 68-69 Bonneville/Catalina.

Thanks in advance for the help!
