I have a white industries crankset. It doesn't have any chainring bolts or chainrings, but I want to use it on a giant cadex.
Is there anyplace I might find chainrings for this or would I just have to steal them from another older crankset?
These are the older style, and when I looked around all i found new was 4 bolt chainrings for MTBs.
Your question doesn't make any sense. Current model White Industries cranks attach the chainring in a totally different way that doesn't use chainring bolts. You can only use chainrings that are made by White Industries.
However, if older White Industries cranks did in fact use 5 bolt chainrings, just measure the bolt circle diameter to determine what chainrings you need to buy or swap. Once you have the bolt circle diameter, try Universal cycles: www.universalcycles.com

If you have something like this (http://www.whiteind.com/cranks/mountaincranks.html), you need a tool (http://www.ride-this.com/index.php/white-industries-lock-ring-tool.html?source=googleps) to remove the old ring & replace with this (http://www.universalcycles.com/shopping/product_details.php?id=31104).
To help find your B.C.D. (http://www.sheldonbrown.com/gloss_bo-z.html) on 4- or 5-bolt rings, print & use this ez chart (http://urbanvelo.org/chainring-bcd-gauge/).

it is indeed 5 bolt, with BCD of 110, 74. But when I looked on ebay it seems like all the mtb cranksets are 4 bolt now and no one seems to be selling the older 5 bolt which have the 44 33 22 teeth count rings.
Or if they do have them they are like $100... so why even bother with the older stuff?
