no
Yes it will.
yeah i did it
1989 Chevy s10
No it will not SORRY.
It will fit in but you will have to swap all the electronics, wiring harness's, fuel pump and fuel lines, etc with it.
The engine will physically fit, however the wiring and electronics will not hook up, they are quite different, as is the fuel system.
Not possible without major fabrication.
In general, many parts from a 1989 Chevrolet S10 can fit a 1991 S10, as both models share a similar platform and components. However, specific parts may vary, particularly if there were changes in design, options, or engine configurations between the two model years. It’s best to verify compatibility for the specific part you are considering, as factors like trim level and engine type can affect fitment. Always consult a parts compatibility guide or a knowledgeable mechanic for confirmation.
