Any Ideas On Bx Loom Bits Missing

[blessed6383 0]

hi guys just wondering what can do as my loom i bought has the ignition amp/ coil piece missing

 

is it possible to source the plugs and build my own from standard gti bits or is there anyone who makes the small piece i need or should i just write the citroen loom off as a loss and just buy a 405 mi16 loom and start all over again?

bit pissed as would mean more money wasted but if its only thing to do guess its got to be done
