it will go far beyond removing both fenders. rust never gives us an easy fix.
I would advise against welding something solid between the body and frame. since there needs to be some flex that will force something else to bend & break.
Kudo's to RockAuto.
ordered these yesterday at about noon, arrived this morning via standard shipping.
Dorman 924-310, total plus taxes & shipping about $61.
they are larger than stock, about 14mm or 9/16"
they do come with the usual Prop 65 warning, so don't have sex with them in California.
put the O'scope on and monitor as you turn the wheel slowly by hand.
then compare to the other wheel at same speed.
if the amplitude is different try moving the trigger ring closer to the sensor to increase it.
