1967 4 door catalina (air bags)
 

Anyone ever install an air ride system on a 67 bonneville or catalina? Looking for a kit that doesnt need too much fabrication to install the airbags or airshocks. Anyone have any ideas?

I'm pretty sure you're going to be fabricating - last guy I know did a '66 and there wasn't any "kit" that you just buy and toss on in a few hours. The Impala\Chevy era stuff is popular and probably the closest you'll get to a bolt in - and it'll still need modifications since the suspensions are different between the 2 car lines.
