skoda vrs high pressure pump help

hi im new to this wondering if any one can help

the problem is i bought a damaged fabia vrs 2006 blt engine code and the high pressure diesel pump has been broken and im wondering if i could put one from a spare engine i have but its out off a 2004 fabis vrs asz engine code thanks

ps they look very simaler but the asz pump looks same but it has a plastic cover over it where as the blt one is all metal
