I've taken the 4 speed out of my 77 and am putting in a 5 speed. I am also replacing the clutch. When I took out the throwout bearing I put it in my parts box not paying attention. Now as I look to get I have 2 in the box 1 with a short shank and 1 with a long shank. Which do I use?

use a new one.

always replace them when you are there.

they are cheap and if it goes bad 100 miles after you get her back on the road then you will wish she had a new one....

c david, I am using a new throughout bearing I'm just not sure of which shank to put it on the long or short.
