My dad bought a D100 and a W200 new from our local dealer in 73 and both had LH lugs. I still own the W200. 72 Satellite Sebring Plus 440, 72 Dart 5.9 4-spd, 68 Valiant, 73 W200, 78 D100 sb, 78 D200, 98 DAKOTA, . Moparmarks Parts & Restorations Desert Mopar Metal Grand Jct.

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it. JB Rhinehart, Realist A-Body's RULE!
