Dean do you know of anyone who has those springs in stock?
I waited for over a year for the last set I ordered and they never
arrived. I got a refund, since it was a reputable company.
The only place I've had any luck actually getting them in the past
year was from eBay when I bought the whole rebuild kit. ~$150
And I agree, replace them all while you're at it.
Here's a thread
about my last ROR rebuild.
