Hello from Manitoba
 

Just bought a 2005 Blazer LS. all stock. I Have been reading these forums
and found some great info already about steering and tires.. But my first
upgrade are running boards. I have found many choices for the 2nd gen
Blazers but they only say they fit up to the 04' would they still fit the 05's
and if not what choices are available for the 05'
Thanks in advance for any info..

Welcome from Wpg!
Not sure about fitment... call & ask for bolt hole specifics & HOW they mount.
Either way you can still drill a 7/16 hole or so for a bolt or 2 & not mess up the integrity of the frame.
Personally I'm going to (eventually) make my own running boards or find a pair of hummer auto extending/retracting running boards.

welcome from florida.
send me some cool air lol. (112 F with heat index) today
yours is a 2005 did you get the last one?

Welcome to the forum

lol would like to but even up here we are hitting the 90's F
but with humidity feels like over 100F.
Funny you ask if I had the one. The VIN is K so it was made
Linden NJ. in the last year before closing and I read somewhere
this week that the last Blazer off that assembly was a white one !!
so.. who knows !! lol

welcome so you think running boards or nerf bars hmmmmmm
