Need some help. I dusted off my old Rostock Max v1 (was equipped with an e3d v5). Upon examination it turns out after we moved a bunch of stuff got yanked out. Thermistor is a goner (no replacements), the heater cartridge (but i have replacements) is done but the body, fan, heatsink, heat brake, heater block, nozzle remain intact. I was wondering if any of these pieces could be used to turn a V5 to a V6? I.e. could i keep the heatsink, heat brake . . . and get a new nozzle, heater block, thermistor. and essentially have a V6? Not sure what is compatible?
