You probably got 4-110mm hubs off ebay. As long as they are not 350X or 85-86R, they should work. Your new rims will work if they are 4-110mm.
The ones on your 82R are 4-130mm and sound like the original 2 piece rims (hense the 8 bolts.) 4 of them hold the rim together... the other 4 hold the rim to the hub.
Put the new hubs/wheels on as a unit. Take off the old hubs/rims as a unit.
