It there a difference between the driver and passanger side rotors on a 89 full size blazer??

 

most of the time rotors side to side are the same. only if the rotors are directionally vented are they different side to side.... heard of fords doing this but maybe chev did it also.

I only ask because i ordered a rotor. After removing the old one i found out the bearing seat wasnt as deep on the new one. Maybe its for the s10 blazer. Ithas manual locking hubs. Would that make a difference on the ID, as opposed to the automatic locking hubs?

 

possibly. bring in the old rotor and have them match it up.
replace both rotors or you are asking for problems.
