Non-Bellcrank Brake Booster

I don't really like how the factory brake booster/master cylinder angles down on the 67-72's. It seems that conversion kits also use the bell crank design and pictures seem to show it to angle down too.

When I converted my 66 the kit used a straight pushrod and I simply connected the pushrod to the pedal arm. I can't remember if I connected it lower as it normally would be. I don't think it could have been lower as the master cylinder is level.

My question is why can't I do that on a 68? Is it a firewall bolt-on compatibility issue?

Has any body tried this?

Re: Non-Bellcrank Brake Booster

This is Capt. fabs bracket installed on my 70 with a 9 inch booster. Don't have everything inside together yet but looks straight forward to hook up. There was a guy on here used another pedal linkage as a bellcrank under the dash looked promising. I didn't find it my saved threads. I think the factory used that bellcrank to clear column shift linkage under the hood with 11 inch booster.The 9 inch booster clears my tilt column linkage fine.
