Customer q:

I am looking at getting some exhaust header cutout plates to cover the cutouts on my exhaust. I am looking at something like SKU #555-30755. I'm not sure what size I need. Can you tell me what the measurement is from bolt hole to bolt hole measured from the center of the holes? Hopefully that makes sense. Thanks.


engine = 454

make = Chevrolet

model = 3100

trans = t400

year = 1956
