like i said in the other thread, I fixed one on a TJ by "rigging" a part that was similar but not specifically for the particular tj but it worked, with a dab of superglue gel

and a little nick with a pocket knife
depends which piece is worn/broken/disintegrated
it's kind of one of those deals like the pot-metal square tab on the back of older like 78 olds cutlass ignition switches that after about 10 years half the time the entire ignition switch would come out when you went to remove the key??
stupid little part, and they typically want you to buy an entire steering column to get that one piece
junkyard hunting is fun, just need the guts not the ignition switch itself, the switch itself should be fine, just a few tabs and plastic rods and junk in there unfortunately
