I'm considering buying one of these off of a '74 455, as my '67 425's starter brace is missing. Starter is OEM so it should bolt right on, correct? Can't think of any reason not to go with a heat shield variant of the brace except for originality.

Also any specs on what size/thread of bolts I'd need to secure it? I know right off that the bolt that threads into the engine block is long gone.

Thanks!

 

What driver side exhaust manifold are you running? With the stock single exhaust crossover, the heat shield is worthless, as the manifold and pipe aren't near the solenoid. The stock "S" dual exhaust manifold requires a special heat shield due to the configuration of that manifold. No, I wasn't able to find one when I put the "S" manifold on my 67, unfortunately.
