904 Slip Yoke, Drag Race Damage, Please help !

Call my friend tell him Marty, supershafts sent you, 515-282-9996, ask him if he is still making the 1310 version and then you'll need either a 5-353 or 5-788 spicer joint, then when you finally get rid of that factory shaft you can go right to 1310 and lose that old dead detroit series
