Reading through all the posts in this thread as far as I can see the only questionable topic would be whether to use a single or dual diaphragm booster. Those who have done the conversion and are using the single-d booster say they're sufficient and that includes myself. Although it does work fine IMO, there is something to be said about why MaMopar engineers designed their disc brake systems to be used with a dual-d booster. That said, use your own judgement. The best decision you can make is what you feel comfortable with because you will have to live with the results. If there's even a question in your mind about using a single-d booster, get a dual-d booster. If you decide to stick with your single-d booster then at the least get it rebuilt.
I have a disease, it's called "IDE" I document everything LOL! I really do it just so I can remember what I did... and I enjoy sharing my results with others if it can make their lives easier. When embarking to do my drum to disc conversion I initially acquired a '70 spindle setup. When I was just about ready to start the conversion Carl K. happened to turn me onto a '73 spindle setup - so I went that route.
The documents I'm providing the links to are "My How To/Steps I Did" for doing a front disc conversion along with some other useful information. In my research I compiled a lot of data, sorted them out and put them into an easy to read format. I've written one for 69-72 Spindles as well as one for the 73 Spindles. While the document doesn't lead you 100% step by step nor give torque values or instructions of how to bleed the brake lines, I'm confident the material is sufficient enough to assist one in doing a front disc conversion with minimal effort. Consult your FSM for information needed not found in these documents or just ask - there's a wealth of information and experience out there between all us members.
The files are in a pdf format and it would be best to download it and print it as they may not be kept on the server forever.
Too bad there wasn't a depository on this forum with specific categories to upload document files to. It would definitely be a good resource area for everyone.
