I looked at the brackets that are currently welded to the cowl, there is one on the engine side near the brake booster, then there are approx. 5 that are welded to the inside cowl (behind the dash/instrument cluster) running from left to right (those probably hold the harness), the one in the photo is somewhat larger (heavy-duty) and as far as I can see bolts to something. Probably goes to the speaker attach bracket but not sure, I'm almost positive it came from around the dash/instrument cluster area because thats the bag it was in from 15 years ago. Any photos of the inside dash area would be appreciated. thanks
