Anyone know where you can search a fork spring by size/dimensions?

I’ve got a xr500 with 91 cr forks (there awful I know) that was converted to supermoto and I want to lower the forks. If I can I would like to add a spacer to the dampening rod and find a shorter spring so I don’t have to try and move the spring perch. Stock spring dimensions are 38.3OD x486mm. Ideally I want to lower it 1.5” so I need a spring that’s ~38.3x450mm. Am I on the right track?  Open to suggestions.

The closest I see is a pre AER KTM 85 at 38 x 425. You'd need a 1" spacer and I make no guarantees but it probably would work without worry of coil bind. Your other option is to call them directly and they can custom-make you the exact size and rate you need for an extra fee.

Thanks. I also found the adventure 790 spring is close but has a bigger OD I would need to make sure I have clearance for.
