I don’t think the mini will work on the stock set up which is what I have , do you know more about fit ment
I used a 1992 Dodge 318 starter as recommended by Wilcap, who made the adapter still working well after 14 years of service on my 58 354 truck block.
That gear reduction starter for the 92 318 isn't much if any larger than a junky aftermarket mini starter.
1957-1958 looks like this: Finding a good one may be tough but they are rebuildable so a core may be the route to go.
