Looking for hurst hemi dart specs

Guys and gals. I have been scouring tge i terwebs and coming up dry. I recently bought a 68 dart and am wanting to build a from hurst hemi dart clone.

First question is does anyone have the front and rear fender to ground measurement? Its way too low in the front and i am cranking up the torsion bars to give me some clearance and figured while I was at it i would just stop where the hemi darts were. Anyone have the info ir a source for it? IMG_20180702_190959_459.jpg
