I was going to use the 69 one in a display board for TOPCAT but i never got around to it so here it is.It is quite a bit larger than the 66-70 inserts for the Ribbed caps...3 inches? Also i have the 65 insert and it comes with the used one you see.... $20.00 each for the NOS ones.....$5.00 for the used one with free shipping. Peace WildBill
