88 Lebaron alternator prob

[krcl153]

The alternator went out on my 88 Lebaron so I replaced but when I tightened the belt tension bolt it was so rusted the bolt broke it half leaving half of the bolt still in, making imposible to tighten the belt. my friend said it would take a lot of time and money to fix this. Any advice?

did the bolt go in easy. if it did use a reverse drill bit that should take it out
