Danny the B8A is a direct interchange.It will start in Park and Neutral.That was the change made in 58.Dont worry about the slight difference in the lever.It works fine.To adjust it put the car in neutral on the column.There are several degrees of adjustment on the switch.Adjust it until the car turns over in neutral.The park position should work at that point.If not shift the switch slightly until it does.If the B7A is in good shape you will have no trouble selling it on Ebay-even used as long as it works.This is a common swap among those that are aware of the interchange.I did it in mine-much more convenient.The B7A is the replacement for 55-57 and only starts in neutral.

  

I have 2 NOS neutral safety switches: FOMOCO B8A-15512-B and AUTOLITE B7AZ-7A247-A. They are pretty much identical except the FOMOCO B8A has a little upward turn at the end in the groove on the lever where the column shift pin would be inserted.

The existing switch on my 1956 Crown Victoria is being jumped and I would like to replace it with one of the above. I am hoping that one or both of these will fit and allow the car to be started in PARK and NEUTRAL.

I am assuming the B8A is for 1958 fords and the B7AZ is for 1957 fords.

Can anyone verify that these will work on a 1956 Ford Crown Victoria and that one or both of these will allow the car to be started in Park?

Thanks,

Danny
