Hey guys, I’m about to do full floors from the front to the end of the bed and rockers on my K5 and noticed there’s no rocker boxes on my truck and no sign that they were ever there and I also can’t find any replacement rocker boxes for an ‘85 K5 so I was wondering if the ‘85 models had them at all? Maybe the blazers stopped using them at some point that I wasn’t aware of? If they are supposed to be there where can I find replacements for my year? Thanks in advance guys!

When I cut up and patched the floor on a 78 k5 it didn't have any.

Hoping you can see that it's not there. Just the rocker and a backer piece

Looks good man, I think I’ll be fine either way honestly because I plan on keeping it on the highway and not driving it a lot no off-roading.

Rocker boxes were only used until ’75, there was no need for the extra structure in the ‘76+ Blazers since they had half cabs.
