9" big bearing that I just bought. No third but comes with 31 spline spool. I need a 9" but this one is way too wide for my truck. Willing to trade for another one that would work better for me. 5 x 5.5 and 5/8 studs. Tabs for Wilwood Superlites and links. Has good discs, may need surface rust removed from them though. 66 1/2 WMS. I was told it is the widest one from ford van.
