Thanks, yeah I'm not sure what year they came out of, I'm assuming older than the one you pictured. Mine were power but I never had them hooked up, they had the manual levers to use as well thankfully. The weight wasn't that bad at all, plus with an rb26dett you really don't need to worry about saving 20 pounds.
Edit: I've always assumed they were 944 but they do look slightly different. If you find out mine were something different let me know. They're definitely Porsche at least.
