Hey all. I have a '68 GT with a bad power brake booster. I have learned there are 2 different booster for this car. Unfortunately I have the one that is no longer produced and is wicked expensive to rebuild, if my unit is rebuildable. What I have is the small unit with a v-band clamp. Are there different brackets to install the larger crimped seal unit in this car? I can find this larger booster for reasonable prices, but it does not fit on my brackets. HELP. Thanks, Ken
