Is the 69er the bike with a 26" wheel one end and a 29" one the other?
yes, i want to put a 29 inch tire on the front .

Put this Salsa 26" fork on my Ocoee('99), it is a good one...replaced the old sprung suspension on mine to rigid.
They have 26 and 29 models.

26" rim diameter = 559mm
29" rim diameter = 622mm
So assuming you use the same size tires, you're looking at a 31.5mm increase in rim radius. So I would measure the axle-to-crown (ATC) distance on your current setup and try to get a fork with a ATC of 31.5mm less than that. Make sure to measure when you're actually on the bike to take the sag of the fork into account.
Realize that a few mm is not going to matter. In fact, an inch or two in each direction is probably fine depending whether you want the handling to be "quicker" or "slower."

I'm guessing the bike is kinda on the XC side and designed for 440-ish axle-crown. Measure your Sid's ATC and if it's in that neighborhood and you like the current geo I'd go for the 445.
