Hypothetically a radio from an S-10 Blazer would fit in an S-10 truck of the same year, correct? I'm asking because I don't want to rip the unit out of my truck, to find out that it's not going to work. I'm very limited in the electronics of vehicles also, fyi.

Most GM radios will fit in other GM vehicles from around the same year, since they like to consolidate manufacturing as much as possible. With the S10, everything should be a near-perfect match.

Alright thanks, I was looking at both them today and the sizes were identical.

if you need to know any more info about S10's my email is the same as my name @hotmail, i can tear apart the dash of a 98+ S10 in under 15 minutes heh.
