I know your exactly right Louey.
Some of these rebuilders just throw them to gether with out ever measureing anything, or checking to even see if they are kicking out right. I know I have got them where the would not spin or even kick out like they were supposed too. I have also got the the wrong starters thats why I like to buy them and take the core back later so I can look them over real good to make sure that they are a perfect match.
