LF DISC BRAKE KIT/HELP 67 DART
This is just my 2 cents...
I recently bought my first car which is a 273 1967 Dodge Dart GT
Leave the drums on the front for now. Enjoy the car and then decide if you really need the disc front.
I am sure you will find
MANY other things to spend money on on your car
that will be more necessary.
Also if you want to simplify things in the future you cant go wrong with buying year correct parts, easier to remember what you have when you need replacement parts in a few years.
THAT being said the 73+ swap is fairly easy and with the Dr. Diff rotors (and hubs I presume) being available in 5x4 and 5x4.5 swapping to BBP down the road is easy.
As to complexity and backyard mechanics skills and ability for this swap. I would say it it very do-able. there are some idiosyncrasies with the swap you may encounter, sway bar mounts, caliper orientation, flexible brake line, proportioning valve / distro block (yes you have to have a Disk / drum version), Master cylinder (yes you have to change it to a Disc / Drum version)
Now mind you A LOT of these parts are over the counter parts at the parts store, the nice thing about buying from DR. Diff is the kit form and the help should you need it from Cass.
