Scarifier bits

[4040]

Does any one have or know of a support bar that may be for sale?
(The bar that goes between the hub cap and scarifier)
Even just the cast ends would do.
It would save a lot of work if I could find some for sale.
It needs to be the type with a round bar that screws into the castings, not the double angle iron type.
A picture of what i'm looking for is below.
Thanks.
