Radiator shroud hardware?

[454cid]

I've had my fan shroud out for a number of years and dont seem to have the hardware handy. What is the thread size of the hardware? The bolts that go directly into the core support won't be to hard, but I have nothing to go on for the others.

13MM bolt with a comparable blind nut which clips onto the shroud. size does not matter as long as they fit.

Right on the money assuming we are talking a Vortec era truck. Both my 97 van and 99 Tahoe use those. Go back a few years and GM used a larger diameter bolt setup.

Thank you. Does this work for the two way down at the bottom, that clip onto the core support, too?

I didn't even think about the TBI trucks being different. Yes, I have a Vortec.

I actually did start looking at those sights last night, but was having a difficult time figuring some of it out. The diagrams I was looking at also showed an 11 clip at the bottom, but it didn't occur to me what they were until now. I'll check and see if my originals are still there on the core support. It could be the 454 is different, although, I thought the bottom half of the shroud was supposed to be the same between the engines.

Zip ties will work while looking for a proper bolt.

It's not that big a deal. It's been out for several years. I'm in Michigan not AZ or TX, so I'm not dealing with severe heat.
