Clutch Schimmy
 

I have a 66 mustang with a 289. I put the tranny in and I got the clutch to disengage. However, when I start in first gear the car schimmys really badly. How to I adjust that correctly to get the schimmy out? I was also wondering if anyone would know why a speedometer gear would not be working. The speedo cable is not snapped and it is the proper gear. I would really appreciate some help. Thanks!
