Disk brake conversion

[CaptainAtom]

Hey everyone, I'm doing a rear disk brake conversion on my 67 Charger and need some help because I'm not familiar with this stuff at all.

I'm looking at going with either of these kits for an 8 3/4 rear end. So from the research I've done and casting numbers on the axle I'm pretty sure that's what I have, but if anyone can confirm that from these pictures it would be appreciated.

(This is what I have with the tire taken off)

Now the brakes from Jegs mentions needing to measure the axle hub flange to make sure the rotors will fit on the axle. The problem I'm having is that what's under the tire doesn't look like the picture that shows how to measure it to make sure the rotors will fit. However the picture does look like rotors that are already installed on the axle but since I'm a novice when it comes to all this I can't say for sure.

I really want to make sure I get the right kit and do it right the first time, so if anyone can let me know if what I'm pointing at is this picture is what I need to measure the inside diameter of, or if it's the thing in the picture that has my hand in it, or if I'm missing parts or just anything that I might need to know it would be greatly appreciated.

Lots of members here that know more than I do but Youtube is your friend. Also I did a conversion on my 67 GTX I used a kit from Leed Brakes. It was a good kit, and their customer service was really good.

What you are pointing at with the blue thing is the axle flange, not a rotor. You need to measure the outside diameter of the circle that you are pointing at. The brake rotor needs to fit over that. The other part you are holding is the backing plate for the drum brakes. If I was you, I would order the kit of your choice and work your way thru the process. Lots of folks on this site will help walk you thru it. Use the search feature, it probably has all the info you need already. Another really helpful thing for you and those helping is to really do your research and try to know the name of the parts you are asking about. When I started on this site one of the toughest things was to ask questions when I didn't know the part names. This site is fantastic. Feel free to DM me, I know for me that was less intimidating at first.

Hey, very much appreciated! I was pretty sure what I was pointing at was the flange that I needed to measure the the outside diameter of but I wasn't sure. The picture that is linked in the kit from Jegs was kind of confusing because it tells you about the inside diameter of the rotor that needs to fit over over the flange but the picture is with the roto already installed and since what I'm looking at on my car doesn't look anything like the picture I wasn't a hundred percent sure what it was I needed to measure or if there was some part that might have been missing. I also really appreciate the offer for help with the installation and other questions. I definitely will be! Again you have my thanks!

Rear disc conversions are really more eye candy than function.
Front brakes do approx 80% of the braking. Only advantage of rear disc is driving in floods or road racing with constant brake use that will heat up the rotors in which case you should be using upgraded rotors pads and calipers.
Getting a hard pedal is the challenge on a non factory rear disc brake conversion.
Upgrading the pads and rotors will do more for braking improvements.
Just an honest opinion.

I appreciate the honesty, it a long story and I won't bore you with it but the drums were taken off years ago and then stolen. As it is I might as well go with rear disk brakes.

New drums are a lot cheaper than a new disc brake kit and the headaches that go with it. Not to mention all the other new parts that will be required to have it function correctly.

If I was to do a rear disc brake project I think I would deal with someone who could advise/answer questions and concerns like Dr. Diff.
