Ok, that's great news. I have found several Burbs but none of them had "factory" power seats. I have set of lowback buckets I want to put in my 77 Cheyenne. I would like power brackets, and I "thought" they were available in 90-91 Burbs (maybe Blazers too).
After some research, I can't find anything in the GM brochures that confirms this was an option.
I didn't want to be looking for a Unicorn...
