Mine seem to have gone missing while the exhaust was off th car

anyone know an approximate length and possibly thread type? or at least if its metric standard...

trying to keep the trips to the hardware store to a minimum...

Thanks

I just put on a new Magnaflow cat, rear Y with crossover and Magnaflow mufflers. I had a little trouble aligning my mufflers and think that the cat is not seated fully which causes the y to sit too far towards the passenger side.
I have been debating whether to crawl back under the jack stands today or just wait till it warms up a bit more.
Let me wait till the wife gets home in an hour or so. I like having someone available to call 911 as I am always paranoid about being under those jack stands (even though they are heavy duty and the car sits solid on them)
I will remove the bolts and take pics and measurements. Seems like they are 14 MM.
Car is a L98 91 coupe.

thanks man that would be a huge help...

13mm, 2 5/8" in length. Unable to determine thread pitch but maybe you can print this out and take it to the hardware store. The replacement bolt could be a bit longer as it does not bottom out.

thank you so much man! thats a HUGE HUGE help. I certainly owe ya one
