B21 waterpump same as B2** waterpump ?

Title says it all..

My '78 242GT needs a new waterpump, and I still have a new OEM volvo waterpump laying around for B2** engines.

Never looked at them actually.. so, are they the same ??

B21/23 is not the same as B230. One has a 5-bolt pattern, the other is 6 bolt. One uses a bolt on the top side of the water pipe, the other has a bolt on the bottom side of the water pipe (the one running under the exhaust manifold that is bolted to the water pump).
