51.43 inch Driveshaft

I've got a couple of these. The original application is for 67-69 Cuda/Valiant with a 904 or 833 with a 7.25 rear, BUT, it will also work in place of the 51.53 long shaft used in the 67-up Darts with 904/833 and 8.75 rear. The .100" difference in length is well within the factory margin of slop. Asking $75 plus shipping each. PM me if interested. Thanks FABO!
