Well folks I finally got the 409 Impala back on the ground, this bushing replacement job turned out to be a real Pain in A$$ !!! Upper A/arms were a bitch to get off, had to cut the bolts leaving enough to press out after arms off. or take manifolds & strg. column out. Lowers fought me all the way but didn't give up!!! Put a "GOB" of grease on top & bottom of coils for good measure. Backed it out of shop today, no more "gronking" from suspension, installed 4 B/joints, new gas shocks & sway bar link kits. Will get it too alignment shop as soon as "salt" gone from roads & no more snow!!! Looked at my 64 Pontiac Parsienne [Canadian] wagon with SBC & there's tons of room to manifolds!!! Glad this jobs done .getting too old for this "$hit"
