General twin 40's inlet manifold for 1300 128 engine wanted

[Scottj]

hi,
im from southern Ireland and im looking for an inlet manifold for a set of twin 40's to go on to a 128 engine. The carbs are verticly mounted i.e the inlet manifold would come out from the head and turn 90 degrees up to meet the carbs. It is slightly different to the x19 twin 40 manifild in that the x19 one is not 90 degrees.
If anyone can help please pm me.
Thanks
Scott
