Thanks for the info, two more questions though.
In your first post you said it was a series 4800 which would seem correct (#48 battery size) now you say its a 8400?
You say same spacer under clamp, do you mean the rubber pad that is snapped between the clamp wires, or there is a loose spacer?
The original just uses the attached pad.
I will add it to the list and maybe buy it myself as my battery was made in 2003, I may be hanging by a thread with it.
