I have stored a spreadsheet of Cobras here:
https://docs.google.com/open?id=0BzD...UFDTXRHb3ZuMzQ
or here:
https://docs.google.com/open?id=0BzD...UFDTXRHb3ZuMzQ
You can view this spreadsheet online with Google spreadsheet or go to file and download the file to your computer and open it with Excel. The first column is the original Cobra. Each column has another model (Superformance, ERA, Kirkham, etc) with the replica's specific dimension or description. Please update the manufacturer of your choice and email it to me at
WFridrich@comcast.net and I will update the spreadsheet at the link.
Please remember this is a draft and work in progress. If you want to add a new criteria, dimension or spec, please feel free to do so and send it to me. Please avoid words like "best" or "heavy duty" and be more specific. I expect I will know what everyone thinks about this based on the response. If no one responds I'll know.... Thanks!
