You could also try installing an OD Speedometer. I might have one if you want me to look.

The Standard Series V speedo is a part number SN 5324/50. The overdrive
Speedo is a SN5324/52. All North American Alpines from B94102641 to
B395010312 had 4.22:1 rear ends from the factory, with or without OD. I
have one of these SV's in my shop right now and I am installing a 3.89:1
rear end in it this winter for a friend. This car is non-OD, 4.22:1, and
has the SN5324/50 speedo. This is a good honest car and falls into the
serial number range for this 4.22:1 problem. I'm sure that it came from
the factory this way. My friend, the owner of the car, says that the
speedo is no where near accurate, and it suffers from high revs. He
can't even drive it on the highway. I think that some of this is due to
the size of tires that he is running, but I'm sure that changing the
rear end will make things close to right. At least a much more enjoyable
car to drive. Robert, I would go ahead and swap the rear end for a
3.89:1. Drive the car and see how the speedo looks. If it's still not
right, I'm sure someone on the list will be able to help recalibrate it.
I understand that Smith's Industries will recalibrate them for you. You
can also try them. I hope I've been of some help. - Ian
