S-1C weight and balance

[Gecko]

Hi Guys,
I’m hoping someone might know which weight and balance / C of G figures to use for my short fuselage S-1C with Sparcraft wings?
I am inclined to use the S-1C figures which among other differences, seem to have a lower gross weight and also allow a more forward C of G than the S-1S.
The aircraft has been weighed but we don’t have any of the original data so need to start fresh with calculating the limits.
Any suggestions would be appreciated.
Thanks
