Easy installation! This 1/8? thick roof can be riveted, bolted or TIG Welded to your existing A, B, C pillars. This is a one-piece aluminum roof with no welds. Any welds visible in pictures are after installation. If using rivets, use only 3/16? stainless steel fasteners such as those we sell on our store in 100 pack quantities. Aluminum rivets are only about 1/3 the strength of stainless steel. This item ships by Fastenal to your nearest Fastenal. You will be notified by Fastenal when it arrives for you to pick up. We can also offer door to door service, but it will cost more than shipping to Fastenal. Use this item with our ?iron curtain? and hard doors for a complete hard cab. IMPORTANT! The number one complaint we receive about other hard tops is they always LEAK because they are 2-piece tops. Our tops are single piece and never leak.
