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?

Kens have the same amount of static play. My SWAG is that if the the center of the hub was to be load carrying, it would be an interference fit from GM, and it is not - even the OEM parts have a small amount of play. The bolt holes in the spindle are way larger than needed for the M10 bolts, so they cannot react any movement of the hub. Proper torque on the hub parts, and friction on the hub to spindle surface are what needs to keep them located. I'll tear down Kens soon - I want to replace the fasteners on the LF since it got hit. I'll look for evidence of fretting, which would indicate the friction is not adequate to hold them in place.

Alan, yes I concur there is a minute amount of play with the OEM hub, but it alarmed me with the amount that was in the hub adapter as compared to the OEM hub. That bent wheel picture from Ken's car came off the LF? Thats a hell of a hit. That must say something about strength of the hub and how it's fastened.

@ Stan - Would you utilize this hub adapter on a 4th gen?

Roy can you share any more pictures? Thanks
