Master Cylinder Installation Issue

[CRW-FK5]

I'm replacing the master cylinder in my '70 R/T Charger (manual brakes) and the re-manufactured MC did not come with pressed in studs for attaching to the firewall like the one that was in my car.  I was going to just swap out the studs to the new MC but found that the thru holes on the new one are too big.  Has any one else come across this issue?  Do they sell MC's with the studs already in them (haven't found any yet)?  Will I need to use bolts instead (would be a PITA tightening)?

Yes same issue for me. I used small visegrip pliers to keep the stud from spinning.

Thanks.  Will give that a try.
