There are two holes on the Halcyon plates outboard of the harness slots that the system bolts into. A quick look at various plates on the DGX site show that some have holes in similar locations, some do not, but it seems that the spacing and location would have to match exactly.With this harness system, can it be used on any standard BP or do you need to use it on a Halcyon BP designed to work with it? And if not can a standard BP be modified to make it compatible?
