Mk 2 Welch carrier Convoy lites "SIZES"

Convoy lites , I'm getting 3 C.lite's 2 for front and 1 rear , now can some tell me the sizes for the 2 front ones. one(right) goes into the pol can holder and on the left a convoy lite goes into the bracket on the left front armour wall, and what size goes into the rear pol oil holder, also i'm looking the swivil mount that is attched to the mk2 swivil headlamp , setup is like the welsh carrier up front, and or the left convoy bracket also. but would like the correct sizes for all 3 c. lites. thanks
