I'd like to use this distributor but I don't have an info about what it fits and if there are parts available. Can anybody help me?
Do a little search here on the HAMB. There is a list of almost all of the old Mallory distributos numbers.
HI-without seeing any more of the dist. it looks like a YL 482-that number would be for Chev V8 except 348-409 and tall deck truck motors.
Parts are readily available for YL models, Mallory Ignition is a Holley brand. https://www.holley.com/search/?q=yl
