Company Profile – About Us Your Partners at C5 Diff, have a combined expertise of over 60 years in the Corvette marketplace. We look forward to servicing your needs and to help you with your projects. In 1962 Raymond Lewis Leicht, Sr. purchased his first 1961 Corvette Convertible. Then came a '58 that needed a rear clip in '63. In '64 he got a '57 “Fuelie” and then a wrecked '63 Split-Window. This was the beginning of Lewis Auto Sales in Tullytown, PA. A business that specialized in buying, selling and repairing Corvette Salvage for over 20 years on a full time basis. Another aspect of the business was Lewis Chassis Works, that developed Race Car Frames and Components for the Drag and Road Race Enthusiast. Even after developing other business interests, Ray continued to deal with Corvettes on a part time basis. Always maintaining a deep desire to keep the mid-year legend alive. Linda Leicht has been a professional involved with the medical field since 1988. In 1999, her enthusiasm for Corvettes became more than a hobby. With her husband, they began to buy and sell mid-year project cars to other enthusiasts. That was the beginning of vetteseller.com. The rest is history! Vetteseller, inc. has provided hundreds of project Corvettes for Hobbyist to enjoy and restore, over the years. It was a natural transition to get involved in the Restomod Chassis, due to the need to replace the rusted out Corvette Chassis. Research began in 2003, to find out what the best unit was on the market. With the demand for upgraded suspension on the older Corvettes it became evident that there was a need for a Replacement Chassis. Along with the need for a Replacement Chassis for the "Original Corvette", there were a number of companies manufacturing complete bodies that would also needed a “New” Chassis. After careful consideration, The Street Shop Inc. C2/C4 was considered the best choice for a Mid-Year Replacement Chassis. We purchased three chassis to become an “Authorized Dealer”. After six successful years of being a Street Shop Dealer, and a desire to do things a little different, we decided that a new Design and Concept was the way we should go. Safety was the First Concern. For our C1/C4 Chassis, we decided to use 3”x4”, Box Welded Tube. The Box Tube used on the Chassis is "A500" Structural Steel with a .125 Wall Thickness. All Joints, Brackets and Attachments to the Chassis are "Mig" Welded on a dedicated Jig Table, with Permanent Fixtures to avoid variance and distortion from one Chassis to the next. This process assures exact replication of the Chassis. The Second Concern was the Handling of the Chassis. Exact GM Specifications and Geometry have been maintained throughout the design of the Chassis. Even when Components were narrowed or modified, they were kept to the "Factory" Dynamics. The Third Concern was the Ride of the Chassis. It was decided to develop the Chassis so it could use an "Original" Style, Front and Rear Transverse Fiberglass Spring, or have the Option to install aftermarket Coil-over Shocks/Springs. Our last Concern was for the Durability and Appearance of the Chassis. For this cause, we decided to use a "Five Step" process. All of the welds on the Chassis are "Box Sealed" so that there is no standing water on the inside of the Chassis. After Fabrication, the Chassis is Media Blasted to remove any foreign material used in the prep process. The next step is a Chemical Wash/Prep to further insure proper adhesion of the Powder Coat. A Powder Coat Primer is then applied to the Chassis and Oven Baked. The Final Step in the Process is to apply a Gloss Black "UV" Protected Powder Coat and again put it through the baking process. After several prototypes, we settled on a design that would accomplish our goals for the Chassis. That was the start of Chassis Concept, Inc. in 2009. Chassis Concepts C1/C4 Chassis #7 was displayed at the Olde Towne (Kissimmee, FL) NCRS Swap Meet in January, 2010. The response was overwhelming. Since then, our C1/C4 chassis has been well accepted, and will be jigged for the C5-6 Suspension. Our new C2 and C3 Chassis with C4 Components is also in production. They are being jigged for C/5-6 Components also. Our Corporate Mission To provide the best Replacement Chassis available, and to help Corvette Enthusiasts with your questions. Our Personal Mission To represent Our LORD, JESUS CHRIST in a manner that will bring Praise and Honor to Him, by treating our “Friends” and Customers with honesty and Integrity. The way we walk, should be an example of what we say. Psalms 51:10
