      Thanks Christophe, I made a more accurate model of the Corvette Brake Master Cylinder in SketchUp.

          I modeled the Corvette C5 brake/clutch Pedal assembly also, trying to stay busy here thru the winter.

              I just bought two clk430 convertIbles hoping to make one of them
              into clk gtr- the roof is already off when using a convertible so the structure is strong

              have you sourced a body ?

                I've been re-working the chassis design, in particular the front suspension cross member. The new version flows better with the hood line and isn't as boxy as the first version. It also gave more room in the foot well. Here the 3rd Gen Mazda RX7 Windshield is included, along with a slice of the CLK GTR Body over the driver. That's me in there at actual size, I think I stole that one from Joel. I left my glasses on to see better. The drawing helps work out things like ground clearance, roof height, leg room, cabin width and steering wheel placement.

                The front end uses Corvette C4 components, rotor to rotor including the rack & pinion. I was considering taking out the anti-dive in the upper control arm but left it in for now. Making tubular A-Arms with heim joints was also in the plans but I decided to keep plowing ahead with the stock Corvette parts.

                .
                As with the rear suspension cross member , the front one is made from 1.5" x 1.5" 16ga square tubing along with 1" x 1" reinforcement braces added.

                I source these chassis tabs thru AA Manufacturing in Michigan, USA. They have an extensive catalog of common and uncommom brackets and tabs for suspension, steering and brake parts for race cars, dirt track, sprint and kit cars.

                    Looking good! You're smart to design the chassis and bodywork around a "off the shelf" windshield from a factory made car. I didn't do that for my GTO and am really regretting it now.

                      Thanks Chip, still learning new things in SketchUp and watching a lot of tutorials helps.

                      Joel, its true how critical the windshield choice is and can be the difference between a good car and a great car. I was going with a Solstice glass then spotted a RX7 at a car meet, it looked like a better option.

                      Here's the jig I made to locate the Corvette C4 steering rack correctly in the tube chassis. I used the original suspension cross member to locate the 2 'dummy' lower control arm bushings. One side was made removable to assist it taking it off the corvette cradle.

                          The stock Corvette C4 gave up its center section for the cause. I considered selling off this part but I chose to sacrifice it to save time fabricating the mounts from scratch. And I got to use my plasma cutter.

                            I picked up a used Porsche 997 Windshield to help lay out the chassis width at the front cowl area. I had the porsche glass on my short list of possible donors and came upon a craigslist ad for one at a great price. its an aftermarket glass and the owner was swapping in a OEM glass to keep the cars value. Good for me ! Here I have it modeled in SketchUp, its close in dimensions to the other donor cars on the list: mazda Rx7 (3rd gen) & Pontiac Solstice.


                            .
                            The requirements for the glass were a wide extended curve at the bottom near the rear of the hood, along with a narrowing taper up the A-pillars leading to another horizontal curve across the front of the roof.
                            .
                            The pic below isn't mine but its the same glass. I wouldn't rest my glass on the heads of 2 drywall screws !! ??

                              Here is the Corvette C4 (1984-1995) front suspension bolted up for a test fit. The upper mounting tabs will be beefed up with perpendicular bracing. Next is adding in the steering rack mounts from the Corvette crossmember, I have it trimmed down and clamped in place for welding. I will also see if the stock vette front sway bar fits into the new crossmember. Thanks for following , -Vince

                                How did you get an accurate cad file of the windshield? Things like that are hard to measure.
