Trailing Arm Bolt Size

[nault31]

I'm looking for the size of the bolt that connects the trailing arm to the knuckle. I've had UMI arms and new brackets sitting on my shelf for over a year and I finally took on the project. The old craptacular arms are off, but the bolt that goes into the knuckle/hub was a PITA to get off. Since both old bolts are seized to the metal insert of the arm I'm going to try to find new bolts before attempting to cut off these rusted inserts. Does anybody have a bolt size or an idea of where to search?

I especially would like to find new bolts since these are torque to yield bolts. My first points of search will be Napa and the dealer if I don't hear from anyone tomorrow.

I'll try and measure. But.. why don't you pm me your addy and maybe I'll just send the bolts to you.

I appreciate the offer but I'm looking to get this done today to drive back to school tomorrow. And since everything but those 2 bolts are on I feel pretty close to accomplishment.

I got mine from a dealership. I think they are $8 each or something like that.

I lost the GM part #s but the large bolt that I was looking for is M14-2x90 Hex bolt.
The dealership did it for me, though they only had one and I was able to hammer the sleeve off of the other one.

Thanks for the suggestions.
