The ones I ordered were the 550 lb. ones. Moss catalogue says it will lower

I want to replace the rears becuase they are sagging unevenly, lower on the
driver's side. You can really tell the difference between sides if you look
at each of them in turn.

With that in mind, I think I'll order the stock sized leaf springs for the
rear, and then check the front. The front springs I pulled off my car were
exactly 10" long (free length).
This doesn't seem to make sense because according to my car # (281---), moss
catalogue says I should use 264-375 (RD to 293445), but in your info
provided it says free length of this spring is 9 7/8". How could my springs
become 1/8" longer over time? Anyway, since both right and left are the
same length in the front, and about the correct length, I guess I'll do the
rear first and then adjust the front if necessary.
Also, assuming free length translates evenly to ride height, the 550 lb
springs I ordered originally would lower the car 2"! After careful
consideration, I think I'll attempt to retain the stock height instead of
lowering.
Thanks,
