Just finished doing work on valve body for pro tree brake. Would like to have high/low setup. Seems nobody makes a DIY kit for that. Hate to spend $400 bucks to get option when I really would like the aluminum valvebody(still working on doing one on mill) at same time hate to spend$500 for aluminum one that does not have high/low option at saem time. Now if had one that was aluminum with high/low I would probably buy in heartbeat.
Yea the option of leaving in high off brake is not a must,but as guy who crewchiefed top alky cars and loved tuning part most .I want it as option. If know of DIY kit or mods needed to make work get up with me and lets talk.
