its a challenge, but you can get them out. Pull the wishbone down and block it with a piece of wood to get clearance, remove the top ball socket, pull the small retainer pin, pull out the felt if there is one, then push the stripped bolt up while using your fingers inside the bigger center hole to feed it over to the hole and out. To install new ones, it helps to run a string or wire through the bolts cotter holes, feed it through the casting bore for the bolt. Then gingerly place the bolt as close to in place as you can and while pulling the string, tease the new bolt through. Once they are both in place, align the slots so the retainer pin can slide through and re install the felt and the pin.
