Dan,
Those door strikers are not the standard strikers. Those are ones that Hershal helped me make, and, have to say much more study and positive in door location and latching than the original design on the early cars. So, measurements for the strikers may mean nothing for your car since I think the others are using different things, except for the ones that Hershal fitted and made the same pieces for.
Hershal worked with me for a week, thanks again Hershal, and doing so full time we only got the body fitted. But, when it was done the gaps were the best they could be and it fit well. I'd be paying more attention to gaps and panel alignment than measured dimensions as they take a lot of tweaking. Dan, make sure you left the shims under the front part of the spider because they are critial to making it align well with the front clip.
Robert, you fellows working on my car or are you down there drinking beer, playing golf, and watching races? /ubbthreads/images/graemlins/smile.gif
