I think you’ll find the FC springs are smaller in overall circumference, they would tend to move around.

Suspect they are different... King Springs quotes different part numbers for FE/FC (KHFS-21) and HR (KHFS-01).

Cheers,

My mistake
FE FC are the same part.
FB to EH share the same part.
HD kingpin is different.
HD kingpin heavy duty same as HD ball joint standard spring.
HR different part number.

I'm pretty sure HR spring will fit FB. The after marked HR springs I have are 5" or 126mm outside coil diameter. My FB springs look to be the same 5" o/d.

There is some more interesting info re FE FC front springs.
Sedan springs (7408860) are lighter rating than wagon, van, Ute springs (7410727). So you can beef up the sedan front suspension a bit by fitting wagon, van or Ute springs.
Same with FB EK and EJ

First you have to identify which is which ,did they have a part number stamped on them Ken ? I don't think they were colour coded for warehousing and stock picking , also fellas if you are looking for new ones ,the only ones I could find are King Springs which I bought and they have one size fits all as Harv has mentioned ,I feel in my sedan they are quite firm ...Vern ..

The part no on front springs is stamped on the flat end or upper end of the coil

Following from what Ken said re swapping the fronts for more strength you can also swap the rear leaf spring assemblies to beef up sedans
