Great looking cars guys and the weather looks good too. Need some advice and maybe a little direction. Purchased a barn find 911 Targa that been swopped to full convertible. It has the flared Turbo body wings and whale tail spoiler. It was an unfinished project, stood for ten years by the previous owner after he realised it had been converted to RHD. Its been professionally done so does not concern me. My initial thinking was to restore it back to original but that may be impossible. The car is identified by the VIN plate as being a 1975 US spec model but it has the hammer head front on it. I'm told this is not correct. Any ideas?
