six into six exhaust mounting bolts.

[bigguy]

I've got the cobra six into six pipes. Somehow I've lost both mounting bolts on the left side. It looks as thought the OEM exhaust used threaded studs mounted on the pipes, and the nuts screwed onto them from the backside. My cobra pipes use bolts to go from the center out into nuts welded to the brackets on the pipes.
As I said, some how I've managed to lose both bolts. I don't want to remove one from the other side to check for size because they are a booger to get back in. Can anybody tell me what size bolts they are?

Dont get new bolts or you will have to install two of them on one side.  Might as well remove one to take it to the the hardware store to get two more.  If you can put in the two new ones you can put in 3 no biggie

There are two bolts on each side. Getting them back in is is quite an ordeal. Oleman and I fought with them for several hours the last time we had them out. I don't know if that's because heat and age have warped the pipes or if it's something else. What ever the reason, it's something I 'm hoping to avoid on the good side if possible. I'm hoping somebody else with the six into six setup might know the size. If not, I'll just have to pull one from the other side.

If you only take one of two tight mounting bolts off, nothing should move and it should be cake putting it back in.  If you start to loosen one and it feels "bound" not loosening smoothly, then tighten it back and remove the other one
