Stock build is impossible to rebuild so be careful if you edit it. Too many slots are used up by the stealth armor and endo-steel combo, in addition to needing 6 double heatsinks. Not sure if stock is the best build or not, but no way you'll get that combo of components back
Endo is 14 slots, stealth 12. six doubles is 18, ecm 2 (46 so far), 4 slots of weaponry. 28 left which are 4 gyro, 4 arm actuator, 8 leg actuator, 5 for head internals, 7 for masc/std engine. 78/78, nothing impossible there.
