In sitting the flywheels side by side with the bolt patterns matching, I noticed that the long pins do not match up. Is this something that needs to be fixed by drilling and installing in the same place as the 3B’s? or will it work w/o mod. Were hoping to get this car running in 24 days. Prom is coming up fast!!
