i dont see those holes on my frame. and i found the running boards on gmpartsdirect but they dont show any brackets. where these drilled into the frame? also the center mount seems longer

i guess will these fit the blazer or pass them up?

 

They should fit, but may require drilling...

 

drilling bad?

 

Not unless you do not check both sides of the frame for clearance first.

 

dont quite get what your meaning by clearance.

 

By clearance, I mean that there is nothing on the other side that you really do not want to drill through (brake lines, fuel lines, fuel filter, gas tank, etc). You need to put the running boards up there and mark where you want the holes to be, then check on the other side to make sure you are not going to drill through something that you should not.

 

ok. I was planning on measuring them up and everything. dont want to screw up anything.
