I mean that the 5spd VS the Auto tach's are physiclly
the same...but they are "wound" different.
Example.......I put Urs4 White gauge faces on my ol
Pearl Auto beast (5spd) & the speedo read about 10
miles faster than I was actually going & the tach was
off. When I had the regular gauge faces on the Pearl
Auto....& my recollection is foggy since I don't have
anymore Auto V8's....only 5spd's :-) but,
the tach didn't read what it was supposed to while I
was cruising at 80mph. The tach was supposed to be
sitting near 4Grand..well with the White faces in
while cruising at 70 (which was actually 80MPH), the
tach was at or around 5Grand.
