I have a set of S10 lowering springs, struts, and spindles for the front from my 91 S10 PU. Will these parts fit on the Monte Carlo SS without any modification?

 

no there will need to be some have modification because you putting rear wheel drive parts on a front wheel drive car

 

Thanks for the info, but I forgot to mention that the Monte Carlo is rear drive, 1988.

 

Im quite sure you dont have "struts" from a '91 s-10..lol
Yea those parts go right on. They are the same part to begin with.
I'll give you a boost tho. I took the entire suspension and steering system off a 2003 two wheel drive blazer. Those trucks have a newer bearing design, slip off rotors, twin piston calipers. They look Hella kool!! and work even better.
