These are original version mushroom shifter balls from my 1986 359 ex hood they are not reproductions or imitations I've owned this truck since new and they are original on my 6 and 4 sticks that came in the truck  I restored this truck and changed to a blue leather interior and had to buy a set of these in blue and paidover 500.00 for them . These will fit a 6 and 4 or 5 and 4 and I'm sure other applications . I see these go on eBay for 250-350 per ball all the time for oem not repop you're more than welcome to look to verify
