I took my sway bar and the brackets off last year while I was drag racing. I am putting my front sway bar back on but can't find the bolts for the brackets. 8 bolts total I'm missing. Anyone know the sizes of them? The dealership could not tell me what sizes they were.

Just to be sure nobody gets confused, these are the brackets that bolt to the frame.

I know the four bolts that attach the sway bar brackets to the frame are 10mm.

I hope that helps,

Thanks. Now I know that they are 10mm. I've got my rear umi sway bar already installed along with everything else I've bought over the winter. Can't believe I lost those bolts. Anyone know exactly which bolts to buy? I doubt the hardware store is going to have the ones I really need. I think half the bolts are thick then slim down where the threads are. If anyone doesn't use their sway bar and have some bolts laying around, I'll buy them!

I just pulled my brackets off my 98 Z28 and measured the bolts because I was missing one bolt and had a broken bracket. The bolts I pulled off the brackets were 13mm wrench/socket head. M10 x 1.5 bolt with a 31.5mm UHL (under head length).

I was looking to replace them with ARP bolts so this is the closest ARP match I could find (I'm sure Lowe's or Home Depot would have something close as well if I wanted to do that)

M10 x 1.5; 35mm UHL; 12mm wrench/socket head
Black Oxide (662-1004) pack of 5 bolts
Stainless Steel (762-1004) pack of 5 bolts
p 85 of the 2011 ARP Catalog

Once I add a washer I'm sure it will be close to the original 31.5mm UHL. I hope that helps someone.
