I just picked up a C4AW-B non "N" nodular case with the date 8K15. That one isn't a problem, the problem is the C5AW-4668-C pinion retainer that came with it. The date code I see is either I19 or 119 it's hard to tell.
The guy I got it from said it was from a '69 Boss 429. I suppose it could be with that date code on the case but the pinion retainer is a mystery to me...
