here are the measurements of the plate that presses and is welded on. it bolts to the disc brake hat using grade 8 bolts. hub must be machined and this is then pressed and welded. its better to use 8 hole pattern.

SOMETHING IS STILL WRONG WITH PHOTOBUCKET ON MY END. STILL TRYING TO POST SLIDESHOW NO MATTER WHAT.

so here the measurementsverall diameter. 7.842, inside diameter 4.484, inside bolt holes5.596. lip on flange 0.372, inside flange width with lip 0.773, lip width 0.385, flange thickness 0.581, outside bolt holes 7.05.

this flange is qual to the diameter of a chevy 12.5 disc brake hub.

was hoping pics would post but photobucket wont even put img next to pic. it does story and embedded story. have img under pic and when I click an copy still does slideshow. what a psr.
