Found if for the liftgate right away. It's possible it's the same weatherstripping regardless of door style. Do you know someone with a liftgate to compare to yours?

 

I bet they're the same. The door opening can't be a different shape. The retooling would be cost prohibitive for GM.

 

I had to get mine (for the hatch) through the dealer. Have you called the local parts department?

 

Here is the GM parts page, looks like the would be different.

Back Door for 2000 Chevrolet Suburban 1500 | GM Parts Club

I'd have to call Chevy. I don't see a weather strip on there for the barn doors and regular passenger doors have the weather stripping attached to the truck itself. The barn door profile looks like a rear hatch cut in half (see swoop around 3rd brake light). Too expensive to just "try it", though, at $100 for a piece of rubber and some glue.

 

Here's a pic I found online. Not the best resolution, but looks the same to me. Best bet is still for the OP to compare his to one with a liftgate irl.

 

Welp, this was the OP's first post and he hasn't been back since...

 

Might not remember how to log in. 😁

 

Well, if the OP does return, here is the weatherstripping. Sadly, both PN's have been discontinued by GM, but there is one of them available on eBay:

Thanks for all the feedback folks...I'm here, just a busy week. I can tell you mine has a cut in the center, at the bottom and it appears to be intentional rather than all one big piece. In other words, it isn't from a rip or tear. You can tell there is like a rubber tube inside of the stripping to align the two cut ends, like it was intended to 'plug' the two sides together. I'll see if I can get a picture up here. Having a fit piece would be nice but I just want to make sure the places selling it that way have the groove so it stays on with a touch of glue and I can cut to fit. Oddly, that is a way cheaper option than the eBay sale...sheesh $200+. I can also follow the part number lead further so thanks for providing that. Jacob, your picture looks like it was taken of mine!

That's how they come. Mine, bought from a GM dealer, has the split so it can be rolled up for packaging and trimming for manufacturing tolerances.

 

No inventory at the two or three I reached out to for $130 - $140. I'm not surprised honestly. I could go with one of these 3rd party after-market options, I suppose.

 

If you can buy the right "profile" of weatherstripping, I don't see why a roll of generic wouldn't work. You can get the bends and twists around the bottom of the door with pressure and time or heat.

 

Fortunately I'm not leaking anywhere, just the common wear along the bottom where the curves are and it is no longer attached...it is pretty exposed there and 22 years will have it's impact.
