Crane Ductile Rocker Hardware?

[AMXguy]

What do I need for the Crane ductile big block rockers as far as spacers and springs go? I'm not sure what keeps them in the proper place on the shaft, or where to get what I need now that Crane is gone.

you need 8 springs , you can use the stock hold downs for the shafts

OK it looks like Mopar Performance sells the spring kit fot their ductile rocker set which I'm guessing would work, but the picture shows 4 spacers per side and I don't see those for sale. do the Crane rockers use these spacers as well? or any washers on the spring ends?

with the alum rockers you use a thin steel shim to prevent the spring wearing into the alum , with the iron rockers this is not nessisary but would not hurt , the shims can be used to tweak the rocker tip over the valve stem as well

When I did my last cam swap I wanted to better align the tips with the rockers as some were off center quite a bit so I replaced the springs with spacers.I`ll have to check when I get home but I think I used the Harland Sharp SP031k-SP700 spacers ordering what I needed after measuring with verniers.You can mix and match to get the desired spacing and they have worked fine for me so far.

There are also a couple other companies selling the same style adjustable rockers as the Cranes.
