I have a 73 Rx3 with a 84 13b engine but I need a coolant fan but I need help. I have a two piece fan on my other Rx3 that fits my Rx3 with the 13b but I need help identify what year Rx7 engine. I try 3 different fan and none fits. Please help

 

yep that threaded hole pattern did change over the yrs. shouldn't be too hard to drill and tap new holes.

 

No you didn't understand what I am asking. I need to know what year Rx7 this fan is from. I install a 3roll aluminum radiator on my Rx3 and there is no room from the water pump to the radiator and the only fan that fits is the two piece one in the picture. So I need to know what year Rx7 is this fan from so I can try to buy one. The shaft has to be short.
