Need Inside Window Sweeps 93 Gmc Z71

I am currently re-covering my door panels and the window sweeps are dry-rotted and brittle. I was wondering if anyone could help with a good supplier source or OEM part number. The older model trucks seem to be more available, but the mid 90 models appear to be harder to find.

I replaced mine a couple of years ago and I just ran up to the local dealer and got them, sorry I don't remember how much or a part number, but I don't think that they were very much money.
