Yo BB Height Fork Relation?

[YANDO]

I'm just rounding the bend on a 93 Yo build. I have a Yo fork non-suspension correct I have been sitting on for years and was lucky to snag a Serotta Suspension corrected 1" fork (keep it in the family). The bike has 2.1's tires all around. My question is what bottombracket height should I be looking for to verify the bike really is suspension correct, I think1993 should be but you never know. Is that measured from the ground to the BB shell or ground to the center of the BB spindle and what is the magic number?

Thanks in advance... -John Y.

ground to center of BB spindle> 11 7/8 in.

Cool,
Now is that going to be the numbers for suspension non-corrected Yo fork or suspension corrected Serotta fork?

-Thanks

That's where the BB axle is supposed to be.
