What size bolts for mounting Lakewoods?

[Skrapmetal]

I need to upgrade the hardware on my lakewoods to grade 8 and add a shim, but I can't remember what size the bolts were. I was going to see if I could find some online to order, but it's too damn cold and snowy out right now to get under the truck.

Any of you guys who upgraded the hardware for yours remember what size bolts you got?

The bolt should be 1/16" smaller than the hole. it's either 1/2" or 5/8".

Thanks Ron, maybe I can dig up one of the shims and just measure the hole on those.

Just a quick morning bump to see if anyone else remembers exactly what size they bought.
