help! 73 620 (beebani) disc brake conv, rotors not fitting?

[Dawa]

so ive had these parts for a while and im just now getting around to the install.

here is the problem:

 

when i try to install the rotors, the rotor bottoms out on the exterior diameter of the hub.

all the photos i see, it seems as if the back of the top hat sits flush on the hub.

 

brake rotor is pronto 31310, which seems to be the same pn shared by other companies

it miiiight be possible that the 2 rotors were mislabled/misboxed but all the other measurements/sizes of the rotors

check out with the specs.

 

or maybe my hub is aftermarket and bigger than it needs to be?

 

i wouldnt mind taking a grinder to the hub so that the rotor will fit, but i feel like there would then be a slight imbalance,

so im wondering if maybe i just need to go with a different rotor.

 

also, this rotor is said to fit all three donor vehicles so idk.....

resolved.

went to oreilly w my hub and tries their "brake best" rotors, and they worked.

 

so either: one should stay away from the pronto/31310 rotors or mine were mislabeled.

 

now to see i can return the rotors
