swing arm bolt

[rigger]

I am going to need a swing arm bolt for my 86' frame.

Anybody know for sure if one frome a 400EX or a 450R will work too?

They will physically fit through the hole, but they are both slightly longer and will need a spacer.

I'm not sure why you'd use one though as they are still available and only $35 new. Hardened or greasable ones are usually $65 range.
