How do i attach the clutch cable...

The quadrant has a series of "hooks" on it... sometimes 1, sometimes 2... some 3 The end of the clutch cable has a little metal cylinder looking thing on the end, it is held onto the quadrant by the hooks. Kinda a crappy explanation, but hopefully it helps. Good luck!

Yep.

Also, regarding the hammerin of the holes.

I dealt with the same thing - my quadrant was an RCH off from sliding on. I chose to machine one boss in the quadrant (I only needed a tiny bit) so the quad would slide onto the two pegs with ease. It worked great.

I even ran with no spacers for awhile to see if I could assist some peoples' thoughts about needing spacers. Pure physics means that the quadrant will self-center (the cable takes the path of shortest distance to the firewall - like a waterskiier being pulled to the middle of the boat's longitudinal plane). I added spacers some time later and it mattered-not in how the clutch performed, and my quadrant never danced with or without spacers.

Just my experience in case it makes decisions easier.

Good luck.
