1960 Valiant front disc brake conversion help needed
For what it's worth, I completed my trip to my northern Michigan junkyard and acquired a pair of front hub and 9" braked drums. 1 came from a 61 plymouth valiant suburban station wagon, the other came from a Dart Custom. I think probably around 1970, I don't really know my Mopar, but I did see that it had 13" wheels so I felt that it probably would have 9" brakes.
My choices were heavily driven by accessibility. There's at least 4 more hubs for 9" brakes in there if you bring a weedwhacker, cordless hedge trimmer, shovel and or forklift. The dart i got my second hub was too far gone to lift with a jack.
