i think its a 1979 model engine, but i dont know, what im most concerned about is the shifter fitting through the rx4 floor without cutting. what do you people think?

what year engine do you think it is?

as for propellor shaft, would a rx7 sa22 12a manual tailshaft bolt up to the rx4 diff? my diff is from an auto 12a. also, do rx7 sa22 diff centres bolt straight in to the original rx4 12a diff?

thanks

david
