your welcome
if i find a Timken unit-bearing part # that would work for me i usually go to Stockwiseauto.com to check on things like price and weight
like for example this very lightweight Nissan "rear" unit-bearing (that would be nice for fabricating a front spindle) ...
http://www.stockwiseauto.com/product_info.php/cPath/1106_1229/products_id/20268/Make/Nissan/Model/Rogue/Year/2009after that i hunt for compatible disc brakes at the same site
Stockwise is listing most parts with detailed measurements like for example on this lightweight rear disc
(originally intended for a `98 Nissan 240SX)
sites like SWA.com are priceless for mixing and matching things for a project
(btw "hub reg" is revering to brake disc pilot hole diameter
)
