Under dash hydroboost and MC Conflict '55 Chevy 3100 truck - restomod Already built bracket to house hydraulic clutch and REMOTE MC ¾” bore, power brake hydroboost and ¾” bore REMOTE MC. I already have 2012-2018 GMC 2500 Savana Van hydroboost unit w/horizontal flange, bolt/holes on 3-1/2" cc. I am unable to find a REMOTE MC ¾” bore to mate with the hydroboost unit. However, I have found several flat cover MC with bore size over 1”. I have already installed the IFS, MII power R&P steering, single piston calipers and a stock pump. The MII steering also requires a pressure reducing valve. Questions: 1. is there anyway that I can use the larger MC, remove reservoir and make the MC into a REMOTE MC? 2. Do I have a conflict with my MII rack, caliper size and stock pump with a larger MC? How about that pressure reducer valve? Any options, suggestions will be be greatly appreciated. This is over my head! FLJerryFLJerryEXPERTAug 29, 2023
