Yes, I believe that is the correct cable. However, two things. First, Shaun asked for a throttle cable bracket.
Second, this doesn't say it fits an '86 460. However, I'm pretty sure nothing changed between '85 and '86 and I cannot find one that says it does fit an '86 w/a 460. So I believe the MPC is wrong and I believe this does fit.
