What modification is needed to use Centaur limbs in a DAS riser?
Why don't you ask Jim Neeves? Some of the new DAS risers have std ILF hardware .... check this out.

Change out the ilf bushings to DAS bushings
I would rather have the DAS bushings, Jim sent DAS bushings when he sent my limbs.
I agree with you on the DAS bushings being the cheapest way to go. But the std DAS mounts do not offer the lateral adjustment those ILF plates do.
