Fast , dependable service. Only issue is it would be cool if you sent short bolts for block off plates. The factory bolts are way too long to reuse . But overall great products. Thanks again ! Kenny down in ga!

Usps lost 1st order. Segular resent a replacement. Appears to be a perfect fit for my 1985 small block GM. I wouldn't be afraid to order from SEGULAR again. Great customer service!
