What is the difference between part numbers such as 67178-96A, 67178-96B, 67178-C? These are part numbers for a 96-98 wide glide speedometer.

 

The suffix just denotes some minor difference but no major change .

 

Would you happen to know the difference? Was one more problematic than the others?

 

The letters are for revisions. AFAIK any one of them would work but "c" would be the latest revision.

for the latest part number.

 

What parts do you need?

 

Nothing anymore. I originally needed a speedometer. There were three part numbers I could have used. From the face, they look the same. I wanted to know if anyone knew if one suffix was more reliable than another or what the differences were.
