I have a 1970 Dodge Dart I am converting to disc brakes. It has an 11inch drum with a small bolt pattern and 14inch tires. What do I need to complete this conversion?
Can you use a F body front spindles and upper A arms I know the upper arm bolts up differently but will this work
DGE7070, I am just about done changing over my 4" front drum brakes back to the original non-power K-H front disc. After looking at what Jim V (71GTX) offers....BUY THAT ! I easily have $700+ into this and took over a year to find new original style parts. My2cents.I have a 1970 Dodge Dart I am converting to disc brakes.

Supposedly F,M,J and 73 up B bodies use taller steering knuckles because of the isolator front suspensions and shouldn't be used for the A-body swap.
Actually this information came out of a SA book written by Frank Atkins. And other sources I can't quote right nowThis is utter hogwash. Yes, the FMJ and B/R body spindles are taller. But the change in geometry is almost negligible, and arguably an improvement. Ehrenberg gave traction to that whole idea with his disc-o-tech article, but apparently he didn't bother to actually check the geometry numbers. This article actually checked the geometry, and explains why it's no big deal to use the FMJ spindles. I run them on my Duster, even though it came with A-body spindles, exactly because of the improvement in geometry for wider tires explained in the article.
