Jeff,
I believe they do look pretty close. The uprights I have came from Cobra Racing(George P.). If you look between the rotar and the upright are the bosses drilled and tapped and have a bearing retainer cap bolted to them? Or are they used without a bearing retainer? Do you have a shot of your front uprights with the upper spring clevice on it? On the Cobra Racing site they say the supply McClusky, SAI and others with their parts. So there is a real good chance they are identical to what yours are. That's why the questions was asked about how many manufacturers there are, not just resellers. Thanks for what you have posted.
