I believe these are from a Buick Rivera? What is a realistic price for a pair of origonals?

Pookie,

Those are 45 fin Buick drums which are the most desireable. Made from approx 1954 to approx 1962 (I'm not exactly sure on the years). The later aluminum drums had 90 fins and are somewhat less desireable. As DMW said, If they are still in spec and not corroded between the drum and the liner, I see them go from anywhere between $100 and $250 on the high end. I need another pair too for my next project :D
 
Maximum dia. on 45 fin drums, ('58-'65), is 12.100"...you will need at least .10" for a clean up cut, and maybe more if the linings are pitted...so if they're close to max., and "haven't" been turned yet, there isn't any service life left in them...

...also, Buick aluminum drums are NOTORIOUS for badly oxidizing between the iron lining and aluminum drum, (dis-similar matals)...if your's has that tell-tale white oxidation powder between the lining and drum, they're pretty much junk...there's no way to get rid of it, and it will continue to oxidize, which in turn, pushes the lining away from the drum, causing cracks in the lining, and when you have them turned, you end up with a dangerously thin weak spot in the lining...


I see alot of them advertized as, "alot of meat left"...well, there's no way of telling that until you measure them with a set of caliper's...you can't tell by just looking at them...

Hopefully, this helps....I've got alot of experience with Buick finned aluminum drums, and would hate to see you pay $100, $150, $200, for a pair, do the machine work, install your hubs, and then have them be junk...
 
These were kept out of the elements and have no sign of the white chalking of aluminum to steel corrosion. And it appears to have loads of meat left for life. I will check measurements to verify. None of the fins are broken off either.

Are the prices posted for the pair of each? [S There is no backing plates- just the drums.
 
I want a set of fake ones to put over my disc brakes. Just kidding.
Usually when I sell used rums, I take them down to the parts house and have them measured with the proper too. If a potential buyer wants to pay extra to know they will clean up then I will have them turned. Remember they both have to be turned to the same size too.
