91Bravada

I have a '91 Bravada I am in the process of restoring. It was my father-in-law's last car, he bought it in 1992 from the Cadillac/Olds dealer where my brother-in-law was a mechanic. When my father-in-law died in 2002, the Bravada went to my sister-in-law who proceeded to drive it into the ground. I got a year ago after it had been siting facing downhill in her driveway for there years. The mechanical restoration is complete and I now drive it daily. Next comes the body. The most pressing need at present are the door glass outer seal for both the driver and passenger door, and the door inner panel weather strip for the driver's door. I believe these parts should be interchangeable with the Blazer & Jimmy of the same vintage, but I can't find them. Any suggestions? Your help is greatly appreciated. I want to restore the Bravada to the condition of my '93 Cutlass Cruiser and '94 98 Regenc, both of which are pristine originals.
