So I replaced my tensioner pulley.. I didn't tighten the bolt all the way because when I did, the brand new pulley wouldn't budge when I tried to spin it. I didn't know that's how it's supposed to be, so I loosened it. It ended up falling off while I was driving, along with the metal washer. Luckily, I was only a few blocks from home, and the pulley didn't fall off. I even drove home and the pulley stayed on. I went back and found the big metal washer, but can't find the bolt. I rather not order a whole new tensioner assembly, or make a trip to the junkyard just for a bolt (I've been to the junkyard like 5 times in the past 2 months, there's really nothing more I could possibly need. lol).

Can anyone please take their bolt out real quick and tell me the length of it? I can match the width up obviously, since I have the metal washer.

I have a 305 TBI, 92 RS, if it makes any difference.

 

It would be more than likely metric maybe 12mmx 1.75

 

It's definitely metric, I remember using a metric socket for it. But where did you get 1.75 from? Did you check it?

 

The idler to bracket is a course thread metric so just a assumption the idler pulley to the bracket would be a corse thread metric as well. Go grab one from a tbi v8 truck at the bone yard.
