Ralph,I bought the New Vintage Woodward series gauges and installed them using a technique developed by fellow bolter Danimal.
We used old gauge housings (which were toast anyway) to adapt the new units for a more factory look and to avoid the extra cost of fancy billet dashboard adapters.
Run up 700+miles with the new units and only one problem so far,the fuel sender needs a little adjustment for better accuracy (my fault).
Here's my take on it,I hope this helps.
