Our car was restored before we got it. There are M6 bolts all over the place. When I find one I always replace with 1/4 BSF. It's confusing having a mixture and means I have to carry 2 sets of tools which is irritating.
The Whitworth thread form is actually better than metric. It's stronger and also seems less likely to seize up in my experience. I've always hoarded used BSF bolts and prefer to use them rather than new if it is a visible position. Retains the original appearance for no cost.
I'm not a purist but I do a lot of miles and so fit whatever will work best. To that end I have Hardy-Spicer propshaft, upgraded steering arm, Phoenix crank, lightened and balanced flywheel etc. However I always keep the parts removed as they are part of it's history.
