B18CivicEH2

i didnt know where to post this thread, sorry if this is the wrong place...

i have a B18B1 engine in my Civic EG....OBD1.....and my car stoped runnin...so me and a friend opened the distributor since it wasnt sparkin and we found that the Coil (i believe that's what its called) had a broken piece.. ..the piece that was broken was the NEGATIVE black piece where you screw the POS and NEG wires...
anyway...i have a B20 Distributor laying around and was wondering if i could just swap the coil with no problems??if they have the same part number and could use that with no worries????thanks in advance

i fould a pic of the object online incase i got the name wrong....


ignore the yellow arrow...thats how i found the pic....
