Okay well im running out of ideas i was working on my 83 280zx na and i snaped a bolt off in the block while trying to pull the water pump there is ruffly a half inch hanging out. Ive tried a stud puller with no luck ive also tried to cut a slit in it to see if i can get it out with a screw driver but no luck. Ive been hitting it with pb blaster every chance i get but nothing. I could drill it out but i really dont have enough room between the block and the condensor. Need help asap i dont know what else i can do.

here is a ruff idea how much room i have just no radiator
