Escalade Roof Rack Parts?

[tsb09000]

So I've either misplaced or didn't have it to begin with, but I went to mock up my escalade roof rack the other day and found I am missing some parts....

I'm missing the RHR piece between the roof and end cap (pictured is the LHR).

Is this something I can order by itself? Is there a part number? I've searched the internet and can't find it.

Also, are these "plates" really necessary?

And why does it cost so much to ship these little buggers?? They're cheap enough I guess at around $7 each but with shipping it jumps to $25-30!


So does anybody happen to have this stuff laying around or advice on where to find the RHR piece?

Thanks

I have all four laid out in front of me. They came off my '03 Yukon XL. The front just say L H FRT, R H FRT. No numbers! The rear say L H RR with a number of 15171714 LH, R H RR with a number of 15171715 R H. Hope this helps, Scott
