I have a 87 dakota with a worn out 89 3.9 (but i used my pushrods from the 87 motor along with the cam and regular lifters when the motor was put in).

My Question is are the pushrods the same? wether it's a 87 non roller 3.9L vs 89 roller 3.9L? I have a rebuilt .60 over 3.9L Short Block assembly with rebuilt heads waiting to get put in, but there are some parts that I have to change over to the new motor, brackets, Carb, intake, ect, ect but I was woundering if I need to use the original 87 pushrods? the new motor also has a flat taplet camshaft
