Anyone know where to get the bolts for the elbow to exhaust housing? GM didnt have any when I checked. Also anyone know what kinda bolts they are, specs wise and where i could get them? Also the bolt and spring set on the downpipe to elbow...anyone know where to get a new set of those? The spring went MIA one night and did a great job on melting the Radiator Res.!!! And one more, who makes a good set of plug wires for these monsters!!??
