I put the brake booster in the Bronco this afternoon. Straightforward repair, and not too difficult. The hardest part was jockeying the old one out and the new one in. The mounting nuts weren't too far up under the dash, so it wasn't terrible.
The truck drives about as well as you'd expect a 21-year-old truck to drive. Now if the damned thing will just hold together until I can afford something decent...though my luck with Fords has been less than stellar.
