How long are the bolts that hold the pulleys onto the balancer? I lost mine and need to go get more.

Thanks

I got 1 1/2 inch. Thats ok I need to head to the hardware store to get a few things anyway. Does it matter if they are grade 5 or grade 8?

I'd use grade 8 myself but 5's should be fine. I'm not sure what they are from the factory.
Also, if you're running a short water pump and have one of those cast bottom pulleys you might need a little longer bolts. Maybe 1-1/4 in or so.
They can be a little to long as long as they don't come in contact with the timing cover when ya tighten 'em up.
