The firewall brackets are correct for 54-55 1st series GM truck applications.The average power steering pump puts out from 800psi to 1400psi line pressure. The Hydropower uses this to convert to pressure to apply against the master cylinder. This greatly improves stopping performance and driver feedback. These hydraulic power boosters can be easily installed on an existing vacuum booster vehicle or used to convert a manual brake setup to power with ordinary hand tools and average mechanical ability.\u003c\/p\u003e \n \n\u003cp\u003eFits: 1954 1955 Chevy and GMC 1st series 3100 truck\u003c\/p\u003e \n \n\u003cp\u003e\u003cstrong\u003eKit includes:\u003c\/strong\u003e\u003c\/p\u003e \n \n\u003cul\u003e \n\t\u003cli\u003eHydraulic brake assist power booster\u003c\/li\u003e \n\t\u003cli\u003e1.00\" bore POL master cylinder\u003c\/li\u003e \n\t\u003cli\u003ePOL proportioning valve, bracket and lines (works with front disc \u0026amp; rear disc or drum brakes)\u003c\/li\u003e \n\t\u003cli\u003eFirewall Mounting brackets and pedal assembly\u003c\/li\u003e \n\t\u003cli\u003eLimited Lifetime Warranty\u003c\/li\u003e \n\u003c\/ul\u003e \n \n\u003cp\u003eSteering hose hookup kits available in the Suggested Parts below. These are remanufactured  Hydropower units. \u003c\/p\u003e \n \n\u003cp\u003e \u003c\/p\u003e \n","brand":"Performance Online (POL)","offers":[{"title":"2 wheel disc","offer_id":44023933206562,"sku":"HB2F-T5455","price":795.87,"currency_code":"USD","in_stock":true},{"title":"4 wheel disc","offer_id":44023933173794,"sku":"HB4F-T5455","price":795.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0811\/7642\/8578\/files\/HBK5455_600.jpg?v=1784710586"},{"product_id":"1947-53-chevy-gmc-truck-fire-wall-mount-brake-booster-mount","title":"1947-53 Chevy, GMC Truck Fire Wall Mount Brake Booster Mount","description":"\u003cp\u003eHave a frame mount booster on your 1947-53 Chevy, GMC 3100 and want to move it to the firewall? This is the bracket you need. Bracket is powder coated black and bolts directly to your firewall.\u003c\/p\u003e \n","brand":"Performance Online (POL)","offers":[{"title":"Default Title","offer_id":44024075845666,"sku":"BBF-4753","price":190.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0811\/7642\/8578\/files\/BBF-4753_500W_1808ef23-badf-4c28-95bb-e8ab46649dc2.jpg?v=1784710405"},{"product_id":"1955-59-chevy-gmc-truck-fire-wall-mount-brake-booster-mount","title":"1955-59 Chevy, GMC Truck Fire Wall Mount Brake Booster Mount","description":"\u003cp\u003eHave a frame mount booster on your 1955-59 Chevy, GMC 3100 truck and want to move it to the firewall?
