Do Blazers have an inner rocker panel? Or does the rocker box do that job? My outer rockers are almost gone and I done see any remnants of and inner rocker. Just trying to get an idea of what I'm getting myself into. Oddly, my rocker boxes are in GREAT shape.

Yes on the inside of the curved outer rocker is a flat piece that makes a 90* angle with the floor. Search for rocker replacement images and you'll see plenty of images of the guts there.

Ok, thanks. I can see straight into the rocker boxes, so they are either missing or rotted out worse than the outer rockers. Anybody sell a THICKE rocker set than OEM or reproduction?

wow. That's a big deal. Are the clecos just to hold it or are you going to rivet it in?

**raggedjim** · 06-28-2018, 10:32 AM

I welded mine, that's how the factory did it.

Good luck, Rg

Here is a break away (rusted away actually) view of the blazer side from an old project of mine.

mister.freeze · 06-29-2018, 08:41 AM

thanks for that. looks like I've got some work ahead (x2). I had thought about making an inner rocker out of something thicker to tie the rocker box and floor together, but it looks a bit more intricate than that.

**1970cstblazer** · 06-30-2018, 08:54 AM

The repro panel is a good one. For a Blazer application the rear of the panel will have to be slightly shortened. The panel was designed for a regular pickup cab, but works fine on a Blazer.

If I remive the fender and door, will I see the end if the firewall like in your first picture?

**1970cstblazer** · 06-30-2018, 01:55 PM

The fender, inner fender skirt, and door will need to be removed to see the firewall as seen in the supplied photo.

When I did the rust repair on that part of my blazer rebuild - I was given a free part to test the fitment with a new aftermarket piece - have a look here at my review. It wasn't that tough.

I'm pretty sure I won't need that part... fingers crossed!

SeventyOne · 07-05-2018, 01:31 PM

Hows your B pillar? Also any rot in the floor pan?

If you have floor pan rot your subframe might also be gone.

mister.freeze · 07-05-2018, 06:24 PM

Floor is good at the b pillar on both sides. Just rockers and usual adjoing floor
