i have been using this kit no 3071, i realize i purchased it about 4 years ago. The booster appears to be leaking pressure when the brake is applied. I removed the boot over the push rod and had someone hit the brakes and i can here it leak. DO you offer a replacement booster that i can purchase or know where i can find one that will last?

• will this work with disc front and drum rear? I should have inquired about that long ago. fitment
• Will this setup interfere with the 5.0 upper intake ? general
• what is the bore on the wilwood MC? general
