1947-59 CHEVY | GMC TRUCK, FIREWALL MOUNT POWER BRAKE BOOSTER KIT 17984

NOTE: Booster may differ from picture depending on type of booster options you have chosen.

Part #BBF-T4753

Steps: Read these instructions carefully!
Important: This kit is assembled for shipping purposes only! Be sure to check all nuts and bolts for adequate torque prior to use. Don’t forget! Make sure this kit fits your application prior to painting or plating. Note that chroming or painting the booster can cause it to malfunction if not done properly. Parts that have been plated, painted or modified may not be returned.

1.  Remove the stock braces between the firewall and the steering support. Cut a center hole for the booster 6” down from the lip and 1-1/2” from the center of the first rib using a 2-1/2” hole saw. Removal of stock gauge clusters ease in the installation.

2.  If the firewall has a rib, trim the metal spacer to fit as shown in the second diagram. If the firewall is flat, discard the sheet metal spacer.

    This will not fit the 54 – 55 1st the way it is. If you want to fit it to a 1954-55 1st series truck, the dimension from the firewall to the steering column drop needs to be modified. I had to modify the bracket by cutting the tabs shorter and drilling new holes. The only problem is that i could not reach the back of the instruments because the bracket was in the way. Wiring was a bit difficult.

      We agree and the original post listed this item to fit from 1947-55 when it really only fits 1947-53 trucks. We have since updated our system. Glad to see that it worked out in the end.

    I also have a 1954 Chevy pick up and was wondering
    if you make a booster kit for it . If not can the above fix from Rick be used on the kit now available

    Hi I was curious what the pedle to center of master cylinder offset is? And how far from center of master down to center of peddle is. Ide like to run one of these for my breaks paired with a a wilwood hydrolic cluch peddle and slave cylinder but worry it will set my clutch to far to the left. I have 1951 chevy pickup
