Are your spindles the 1 1/4" or the 1" spindles? That could determine your next choice of action.

Another easy way to tell the difference of the wheels is on the back side of the barrel. If it has somewhat of a cone shape to it, drum brake wheel. If it's flat most of the way from center to lip, it's disc
This.

The 88-98 Lt Duty trucks that were 6-lug used different spindles, calipers, & rotors w/slightly different spacing/dimensions vs. the more common 71-87 spindles used when doing disc brake updates on drum brake trucks. Aftermarket 6-lug rotors for the correct spindles you plan to use (for disc brakes) are the easiest/best way to go.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
