I had a heater core from my old Saturn that I thought
I would use, but as things have come together I find
it might not be the best fit.

Attached is a picture of the Saturn core in the
position and location I would like to have a heater
core.  The left side is the instrument panel, right
side firewall.  The in and out tubes would come out
from the saddle tank directly facing the firewall.
These hoped for positions are depicted by the bright
purple lines in the picture.

Is there a heater core out there which would fit this
need?

Thx...
