I started installing my new tach last night. 3 hours later and it still isn't done. Everything went smooth until I got to the very last step. Installing the two silver bolts that holds the speed/tach bracket to the bottom of the triple something or other. Even if I just try and put the bolts in without anything they are extremely hard to get started and you only get a couple of small turns before you have to start using a wrench. I would appreciate any and all help.
