Important note! There is a small pin/spud that needs to be inserted into the back of the piston area of the master cylinder, before the booster is connected!!! It was found in a very small celephane bag along with 2 screw in hole plugs. Watch this Speedway video for more info: https://youtu.be/W3N0kSwvkQA The video is posted near the bottom of this page on the left

Hi, Part # 91664064:- States 1947 - 1954, But could it be made to fit a 1946 3/4 Ton Chevy Stake Bed, which is currently single circuit / Hydrovac...Drum / Drum. There no pedals or cross members to foul, as its all be removed to fit a 200R4 / V8....How many of the (residual valves) do you need is it one front & one back? Also if it will fit a 46, which is best this one or the Part # 91664060, / which would be cheapest on shipping? Many thanks Ray
