I most have the only E body vert that isn't a wet noodle.. I can jack up the left front @ the frame rail & the left rear will lift at virtually the same time... I can open both doors while jacked up & they close fine... I raise it on my hoist frequently & again I can open & close the doors no problem.... It's been restored for 15 years & I've driven it 60k+ the doors still line up, the hood & deck lid line up, no cracks, no door edge chips...

FWIW If I had it to do over I might consider the US Cartool SFC's but my car really doesn't need them....
