Default Aluminum brake drum help...???

I have two aluminum brake drums, thought they may be a good Ebay item. But I have no clue what they might have gone on, can some one please help? They have GM part number 1255496 cast on the inside.

Some Buick came with these on the back drums. We used a pair on the back of a B/stocker [img]/ubbthreads/images/graemlins/naughty.gif[/img]

I am thinking that the Yenko Corvair Stingers came with these, either as a GM option or a Yenko option, do not remember which.

Some one else just told me possible Buick over the phone, if they came on a Yenko I would freak. I won't be able to sell them if they did, cause they are the closest thing I will ever have to a Yenko.

Measure the bolt pattern and you will know. buick was a 5" pattern not a 4 3/4" GTO/Chev pattern.

A easy way to measure the bolt circle acurately is to skip the hole directly next to the one you place your tape on (be sure to hold it to the outside of the lug hole) and then go to the 2nd hole and the correct measurment is the center of that next hole. Try it and with pratice you will always find the correct measurment of the bolt circle. I learned that little trick from Jerry at burgraff tires here in tulsa years ago. Used to buy a lot of mags from them for my used car lot. [img]/ubbthreads/images/graemlins/scholar.gif[/img]

That is what I did, and I'll up you on that. I used a micrometer instead of a tape measurer.

I'm thinking more and more, these will find away on one of my cars instead of auction.
