Bearings for rear end drums...$75 a piece!!!????

[72CampSpecial]

Need some help finding a good source for inner and outer bearing for my C20.. Being quoted $72.33 a piece for the outer bearing/race and $69.14 a piece for the inner bearing/race!! ...or is this reasonable?

$285 for bearings seems REALLY high?? I just did the front end for a fraction of that!! When i factor in the grease seals and diff cover gasket, new brake shoes..im $330 into this job.

Are there other options here (rear end swap?)

Outer bearing part # on the old bearing: B11630
Inner bearing part # on the old bearing: D11786

'72 C20, 3/4 ton with 3 link suspension.

Pulled everything apart because the outer bearing on the drivers side ate itself and stranded me in the middle of the road when the drive shaft partially walked out of the diff...(see my previous post)

help appreciated...
