I bought a kit with the crimp tool and various clip and cage sizes. I used this on my '52 Chevy truck build for AC lines and for heater hoses - works awesome.
I got all of my stuff from Murdock Supply.
It took me some time to find the site - it had changed since the last time I used them, but I think site essentially links back to Murdock as the supplier.
