Buying a kit for a Pantera, with its far from normal hose routing will likely give you extra hose in some sizes and inadequate hose in some sizes than you actually require. Same with the fittings.
this is the supplier I used for almost all of my material. They appear to have everything in stock, they ship very promptly, and their pricing is competitive.
The Eaton Aeroquip website is a good resource for learning what fittings are available
