[Northkeep] Question for the mechanically inclined.

[Amanda Wallace]

Kevin,

You can call Jim at 728-8250, tell him you are Keigan's hubby, and (after
asking if he has a moment) see if he can give you any ideas, from the
description. He does not have access to the list at all, nor to the net
reliably (kinda hard when moving around 4 or 5 different bays to work on
cars).
