front disc brake conversion

Not familiar with that kit. Can you post a list of parts included in the kit? And just so you know, i did the "stop on a dime" conversion on my 68 Roadrunner about 10 years ago. I was never happy with the way the brakes felt. I spoke to Cass at Dr Diff and he recommended a smaller bore master cylinder. I had a manual Abody disc cylinder. The new late model (ok 90s Dakota maybe) master made a great improvement. Pedal feels much better. Maybe not your issue but I just wanted to share my experience.
