The quality of some of the replacement parts is appalling. I just got a breaker plate for my 9n distributor, it came with a set of points already installed, The plate was molded aluminum instead of steel. it was too big in diameter and 1/32" too thick. I put it on a shaft (transfer punch) with the original plate so I could match it to the old breaker plate on the same shaft and then ground some material off the outer diameter so they would be the same. and also thinned it out at the edges so the spring retainer would hold it in place in it's groove.
Next was setting the gap. turns out they must have installed the points and swaged the axle the points are on to the base plate at the same time because the shaft expanded and riveted the points to the back plate. I found this out because they couldn't be gaped as the slots were the wrong size or in the wrong place to allow them the pivot properly and I had to get them off... that destroyed them so I used the blue streak points I had on the old plate and had to sand the pin diameter down to even get those on. It's running properly now but that was a lot of unnecessary work.
