My 64 Skylark currently has the BPC turn signal switch and bowl. Can I use the Guide switch and bowl? Is the steering column the same for both switch and bowls? I have shorted out 2 new BPC switches trying to replace them and have a new Guide switch on hand. The BPC bowl is cutting into the switch wires as I try to attach it to the steering column. I will need to find a Guide bowl, so any sources for that would be appreciated. Thanks in advance, James Q.
