d16a6 block = d13d2 block?

heyho zsammen…. has already made me a bit more knowledgeable. wants next week arms from d13b2 to d16a6 – then again with my d16z6 head druff. fit the motor holders? netz says: yes fits the transmission from the old? if that remains from the new engine, then fit the drive shafts? mfg alex ps: has anyone already had experiences how far / if you have to expand the nozzles from the d13 loser? original d13 ASB + klumbatsch should stay there….
