1980-1981 Corvette Halfshafts. GM part # 14009998. These use the 1330 series u joints for the automatic cars.
$30 each or $50 for both. They are in good condition except some dum dum num-nut before me had clamped them in a vice and put some small dimple dents in them near the yokes.
Bring your own u-joints and I can press in for $20 per half haft
