Forestay Length for C 16 Early Model ?

[Pacman]

Can anyone here tell me the forestay length for a C16 series 1 (1976).

My boat is in storage so I can't check for myself right now.

I will be sorting through some used sails trying to see what might work on my little boat.

Thanks

I got my boat out of storage today and measured my forestay.

The overall length of mine is 13 feet, 3 inches.
