older Phil Wood bottom bracket question

Help!

I've got an new old stock Phil Wood bottom bracket I want to mount on my titanium mountain bike. Unfortunately the spindle length of the bb is 130. (Also, it's square taper.)

Does that 130 put my crank too far out? I think the usual mountain bike bb is 117...

If I get some older square taper cranks, or some slick new Middleburn ones, can I use this bb? Or will I have to resort to spacers and the like?

Thanks for any help you might be able to give me.

More info needed. Adjustable or fixed drive side cup on the BB? Frame and crank? Best bet is throw what you have on the frame, and see what sort of chainline it gives you.

Too far out? Get a Phil adjustable chainline driveside cup to get things in a bit more on the drive side. Run fewer rear cogs and space the cassette outboard a bit. A couple chainring spacers may be able to move your rings inboard if everything is all too far out.

Or, it may just be too long and you'll need to swap to a shorter BB, Phil or otherwise. Or you just suffer froma non-optimal chainline and replace your cassette and chain more frequently.

Thanks for the thorough reply. I appreciate it. I just don't have the info yet. (I tend to leave bottom brackets and headsets to the LBS.) Cheers.
