Hi, I lost a connecting rod nut for my 93 STS N* engine, can anyone tell me where I could get one, already tried GM but there out of stock and discontinued, or should I just put some regular M8 x 1.0 nut

That is funny

I have never seen one.

All the rods I have seen have bolts. I remember reading about a list of changes for 94. Hmm I guess the 92 and 93 had nuts. I mean the engines built in 92 and sold as 93's.

I would be glad to send you a connecting rod nut for your '93. Give me your address, and I'll send it right out.
