I have the Assembly Manual and it shows there's various codes for the rear springs (left rear sagging on my car by 1/2"). I can do a quick fix with some spacers I think, to level it up but in looking at the various suppliers the cost and type of spring(s) appear to be all over the place as far as a "correct" replacement. On he Hurst Olds, with the 455 did that come with a standard or heavy duty suspension would be the first question and then 2nd what's the correct set of rear springs for it if I just go ahead and have them replaced?
Thanks in advance

You need springs that are equivalent to F41 and/or FE2 suspension options.

When you get to that point, front end alignment specs are also different for Salon, 442 and Hurst/Olds. Use the specs listed for Y78 Salon.

 

Thanks, have this printed off for future reference.

 

Been looking for 75 H/O W30 rear springs - "indicating FE2" and nothing really comes up....just generic "this will fit your 75 Olds with 455.
Anyone have a specific supplier/company with a part number I can use to order rear springs? Thanks.
