The speedometer cable broke on my 1988 Single cab F150 4x4 Mazda 5-speed. Ford no longer makes the part and NAPA was the only supplier I could find. However, the new cable is about 10 inches longer than factory. Will the extra length affect my speed reading?

 

I don't know for sure, but I would guess that it will be fine.

 

I got my answer. The new cable worked fine for about 10 minutes and then twisted like a pretzel.

 

Huh. I'll have to mark that one down....
