1960 Valiant front disc brake conversion help needed

Well, you have a Mopar that even most Mopar people don't know much about. I've never owned one myself, but have read that the 60-61 front suspensions are different than 62 and up. Makes it harder to swap in later stuff. And all 60-61's will have nine inch brakes, too. Now - I believe a 63-66 K frame will swap in, and then you can use upper and lower control arms, as well as spindles, from 62-72. If I'm wrong, hopefully some one will correct me. That will give you broader and more easily swapped brake choices. Nine inch drums are marginal in today's traffic. Ten inch drums are OK with a stock motor. Discs are better. Factory 14 inch A body Ralley wheels will fit. They are 5.5 inches wide. Pressed steel wheels with the small bolt circle come in 4.5 and 5.5 inch widths. For $$$, Cragars are available in 14 and 15 inch versions. There are a few other aftermarket options.
