Having issues mounting the Dulaney hub adapters - F-Body Road Racing and Autocross Forums

So I saved up and bought the Dulaney hub brackets and the SKF corvette racing hubs but have some issues or concerns.

Is there a difference between a 4th Gen LT1 and a 4th gen LS1 spindle in the area of where the hub mounts? Do both spindles have that chamfered area where the body of the hub goes through? The reason I am bring this up is when I trial fitted the Dulaney hub adapters, the lip on the back of the hub adapter did not even come close to engaging the main part of the spindle hole. The lip on the back of the hub adapter only engages in the chamfered area of the spindle hole which gives a rather loose fit and relies on the 4 hub mounting bolts for all its strength and its security. The lip on the adapter is 4 mm high. I am concerned that just the 4 mounting bolts is not strong enough without the lip engaging past the chamfered hole in the spindle or am I just being overly concerned. Are the 4 Arp mounting bolts more than strong for this?

The below video I hope shows what I'm concerned about and trying to explain.
