26"suspension to rigid fork axle to crown?

I've got an old Haro frame with a 26" XCM on it that I'd like to swap for a rigid fork.  Its listed and measured axle to crown is 482mm.  The 26" 100mm suspension corrected rigid forks are all around 440mm and the largest I've found at 485mm is listed as a 29" corrected for 120mm travel.

Do I buy the 485mm or what?

Thanks in advance.

For anyone interested in this topic, my own research has yielded the following information:

Axle to crown on a rigid fork should be roughly equivalent to the suspension fork a2c minus 20-30% of travel to accommodate sag.   

So my 482mm a2c 100mm travel fork should sag to 452-462mm.   

I purchased a Soma Cromo at 465mm.  I've been riding locked out at 482mm anyway. 
Close enough.
