Really cool, I didn't know the spindles were a weak point that needed to be reinforced. I have never seen anyone do that on an impala is it a g-body, Cadillac specific reinforcement?
I wouldnt recommend it but I have seen it done on cars with big wheels I cant say how long it lasted but I would definitely take it to a professional welder and they may still not want to touch it due to the liability you would be better ordering a lift spindle for a truck
I always recommend somthing that uses gas shielding lowes and home depot sell pretty decent welders for just beginning I would try to get something that's 220 powered but I have seen plenty of builds done with a 110 welder I would try to stay away from flux core.
Folks love to whine about paint on rotor surfaces- like you I’ve always owned cars that magically took the paint right off after a few stops and never had an issue 😂👍
Yeah i never really understood it the rotors rust over night and as soon as you drive it the rust is cleaned right off so it will so the same with paint
