I did kind of the same thing on a Challenger several years ago. I had the local hydraulic hose place do the squeezing for me after I fitted and marked the lines and couplings. If you check some of the AC parts places, they may be able to supply the fittings at the compressor like the factory ones that came on the truck the motor came from. You can but all types of fittings and hoses to repair original stuff, so you can make it work for your application too. New hoses for 134 will benefit you, so it would be best to replace them all if you can.
