Hey Henry, you're on your own for them blueprints. No company is going to give away their design.I got freaks tryin' to buy Cheeter prints from me all the time, whatthefuck, why should I take the time to develope something and then give it away.If you must ,the only prints out there are the ones from CobraRestorers. Easyest and quikest way out is to just buy a frame from B+B.

Henry Scheffler 707 Timber Road Harlan, Iowa thanks to both of you for your help. Having more time than money, I have to build it myself. I sure don't want to copy a company's idea, like all these cobra kit car companys did from Shelby -American!!!!! (just kidding)

Another two cents on the subject. I too am building my own chassis. I invested in the 427 S/C plans from Cobra Restorers ($200).

I contacted the dude with the Cobra plans. He is selling a 289 Cobra and a 427 Cobra set of plans. He sells them seperately or will sell both.

He is Jim Thomas, J4MK@aol.com, or see the telephone numbers above.

I am currently copying my plans into AutoCAD. I will be "Reverse Engineering" a 1989 Mustang front clip which is sitting in my driveway. Once I have the parts on CAD I can redesign brackets to use the Ford parts and eliminate the Jaguar set up.

Good luck on your build. I have been delayed for a year on starting the project. I began to seriously sit at the terminal this week and begin to convert the drawings.

Good luck on your build.

Hey Ben I finally got back to viewing the forum.

I got 57 1/4" across the faces of the rotors.

Hope that helps.

Yes. The plan is to leave the entire assembly together.

Then I will measure from each critical point and make an assembly drawing.

The parts outlines will be overlayed on this drawing and dimensioned. That is hole diameters, angles, etc, just as if I had designed this assembly from scratch.

The 427 Cobra chassis assembly will be the basis for the final drawing. The Mustang front suspension drawing will be overlayed (electronically) using the centerlines of chassis and front spindles.

Once this is done, the spindles will be moved inboard to give me the correct width, or roughhly 5/8" per side. Brackets from the original that are not aligned will be erased. Brackets from the Mustang assembly will be erased.

New brackets mating the control arms, springs, and shocks will be designed. The assembly will be dimesnioned so that the chassis can be built to these new parts.

These parts will be detailed and dimensioned for making each part.

The above is what I have been doing for a living since 1966 in one shape or form. The unique feature is that I am applying it to my own project, not my employers.

A point of interest is a Body and Fender professional is selling his means of making these measurements he developed over the years. He has a listing on EBAY with 25 - 30 photos. Enough for you and I to copy and accomplish the above. It is item #601725105.

The principles used in checking parts on a coordinate measuring machine are similar, except he has developed what is known as a "Story Pole" or "Story Board", only a 3 dimensional version.

I had planned to do something similar. I now have the plans to measure these parts to "Reverse" engineer these parts.

The principles are simple. The work a little tedius, but as we all know, the Cobra replicas were "Reverse Engineered" from the original cars models, in one way, shape, or form. It just requires a non-conformist to reject the Cobra-in-a-box, like me, to make it happen. Another individual that comes to mind is our friend "Cheetah Bruce", if I am not mistaken. I not only got a Cobra body from the man, but the acknowledgement that my excentricity is not so far out afterall.

Soap box is put away.

Have a good day everyone.

Along the same lines, I met a man from Mexico today at the SAAC dealy. He bought the blueprints from Cobra Restorers inputed them into Autocad and converted them to metric. He says he found a few mistakes, verified they were indeed mistakes from Mccluskey, and then corrected them. I saw pictures of his chassis, and all the tubing has "Hecho en Mexico" on it. He says it is not exactly 4" tubing, but he has maintained all tubing centerlines. Next he wants to buy an aluminum body because it is more "autentico" than fiberglass. The guy is getting all of his family, including his wife, involved with the build. It was kind of tough talking with him because my spanish is a little rough, but he knew all the parts to a 427 chassis by heart.
