Heat Shields

[NomadTW]

i believe that my rattle is from the heat shields
if it's the resonator after i remove the shields i'll deal

what size are those bolts on the shields

they seem to be 13/32nds

10mm is too small, 11mm is too big

7/16 is too big
3/8 is too small

that leaves that in the middle

and the ones on the manifold seem to be 15/32nds

can anyone confim, i'm gonna go hit it w/ wd40.... see if i can loosen them up
