Speedometer Replacement/Cable/Horrible Day

We have done this on dads waaayyy too many times! As abv said, take out the 4 bolts that hold the steel collar, as well (67 cuda) we took out the 3 bolts that bolt into the floor/firewall, this will help a lot. Do yourself a favor and take the drivers seat out...for the extra 5 minutes of work its worth it!! As for the brass collar, that is supposed to be there, that is a "stop" so the cable doesnt bottom out in the speedo. What we found with dads new speedo cable is that the length after the stop was still too long, so we ground off about 1/8". New cable worked for a bit, but we still have issues. So it came back out before winter hibernation. We are sending his factory tach and his 150 speedo in to Mr Heaterbox. A company here in ONtario that rebuilds/calibrates them
