86 Interstate wheel/disc installed on 84 Aspy?

[DC44]

All: I need some information. I've taken the front tire/wheel & disc off of my '86 "I" and installed it on my '84 Aspencade. The disc on the Aspy is much thicker than the disc on the Int. One of the part #s on the Aspy brake assembly is different than the I's assembly.

It seems I need to either switch out the discs and install the '84 disc on the '86 wheel or install the '86 brake assemblies on the '84 Aspy. The reason I ask is after installing the 86 I's tire/wheel on the '84 A and pumping the brakes the front wheel is dragging. I know there should be some friction as I turn the tire/wheel by hand but it seems to take way too much effort to make it turn.

Ideas? Suggestions? I need to take care of this in the morning, 11/18/15, so I'd appreciate any replies when able.

Thanks in advance,
DC
