You can get brake hoses made from most any hose vendor, just tell them what you need or take one of the old ones in and they will probably make what you need while you wait. You might look into aftermarket calipers etc. as they will be much lighter. I had a Versailles rear end and finally ditched it as it was about double the weight of a standard 9". Ford MotorSport makes a bolt-on brake kit for 9" rears and it ends up being a lot stronger setup.
Parts stores are not going to make them...they would only carry stock OEM stuff but they might have what you are looking for. A hose place like American Hose & Fitting or similar can make them to whatever you need.
