Title: Manual brakes to power brakes
Post by: Swampyankee74 on May 23, 2023, 04:02:42 PM: I'm converting my 74 c15 from manual to power brakes. I purchased a remained Delco moraine vacuum booster supposedly for this year tuck. My manual brakes bolted flat to the break/steering bracket with a rubber grommets where it went through the fire wall. The new vacuum booster stands off on brackets. What seals around the brake pushrod where it goes through the firewall? Am I missing a part? Looking at something wrong?
