RobbMc mini starter

Years ago I bought a set of headers on ebay. I have no ideal what the brand was but they were a tight fitting set that didn't hang low like the Hookers. I installed on my 340/727 Demon and tried all kinds of starters including minis. The only one that would fit was a clockable powermaster. My point is a standard mini starter doesn't always work even on the later A body cars
