What is this part? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm getting ready to do a bunch of rust repair.

Does anyone know what part this is? I can't find it on ClassicHeartbeat, GMC Pauls, LMC, Brothers, etc.

I can't find a schematic that matches. It has rust on both passenger and driver side, so my preference is to replace the whole thing.

The picture is from the driver side, rear wheel well, looking forward. Picture is taken from the front of the rear driver tire looking forward. You can see the back of the driver rocker box (with end cap removed).
You can see the rocker box mounts to it (rusted out on left side), and it also attaches to the polyurethane body mount. Runs east to west.

I will try to get a better picture tomorrow. Tough to get something given the location.

Sorry I thought you meant the part below. Disregard.

It is a cross sill that I think is Blazer specific. I don't know if it is available repop by itself. I know the rear most one is available, will see if I can find a link

Edit: here is a link to what might be it. I would call them and verify that it is the correct position. The picture they have leaves much t o be desired

It's a cross sill like Richard said. Not sure if they are reproduced now, but when I did my Blazer I used a pickup truck cross sill. I seem to recall the only modification I had to do was at the area where the hold-down bolts go through. You can see in the picture there's flat indentations where the bolts go that I had to put in. The pickup truck part is flat in this area.

EDIT; I checked Bill's trucks (near me) and that part is now available for the Blazer. Check out page 153 in the link below part # 27-5117-A

Thanks everyone. I think this is it - was able to use KeyParts + the pics above to find the part and order from Jeggs. (Jeggs doesn't have the image - so key parts link was key).

I wish mine looked like this!
