Sorry - no. I purchased the CalSci large and it installed in about 5 minutes with no issues. Sounds like they simply included the wrong hardware.
Yes the holes are larger on both the Large and the Shorty. When all of the bolts are reinstalled, it's not an issue.
You were right and I was wrong. I reinstalled my shorty yesterday and I compared the hole sizes. The CalSci shield holes are slightly larger than the stocker but when you mount it up it makes no difference.
Yes mine are larger too. but the center bolts seat ok.You are using the larger of the six bolts for the center right?You still have the white plastic washers with them?
... along with the plastic washers will slip right through the holes. ...
