I believe they mount the master cylinder and booster under the floor on the drivers side. I'm installing that under my 46. The power brake setup is a very expensive system but cleans up the firewall. You can even install an off-set type steering column which puts the firewall side of the column a lot lower and just about out of sight. Another expensive item. I think a clean firewall looks sharp and enhances the look of the engine compartment. Bob T
