If you are looking for a leaf spring in the 140 lbs range then the AFCO 20231 would be close to stock.

I’m did a deep dive on leaf springs a few hours ago using the search function. /6 were like 90 lbs springs, LA’s were around 100. Circle track springs were 130, Hotchkis are 130, XHD are 140, and SS are 160 lbs/in.
Looking at factory photos of these cars they appear to sit quite low in n the rear. From looking at the photos of cars refitted with -1” springs they seem to look the same as OEM. +1” springs seem to look a little higher but not jacked up looking.
