71 disc brake rotor part number needed

[swarm49]

I am attempting to replace the stock 1.25" rotor and found that what I bought was a 1.5" rotor, the two look identical otherwise and fit fine too.

I'd really like to avoid the whole change over to the later disc brake assembly and just get a new rotor.

Any help is much appreciated.

Really need more info. If it's a 1971 C30 with dual rear wheels then

But I'd need more info to give you a more precise answer.

It is drw, but the old rotor had a big hub like the photo shown, only it was a 1.25" wide rotor, not 1.5" wide like the rotors I bought

I had the same problem last year with my dually. I just went ahead and changed it over to the later model stuff. I think it will save a lot of headaches in the future. The later stuff will be more readily available in the years to come

I understand but I have a road trip scheduled for next Friday and I really need to get these orders in place by then
