I've always prefered a split wishbone over haipins, and this car is no exception. What do you like? you don't prefer one over the other? Even just a little?
I prefer hairpins but I've never had to choose one or the other I always either had one or the other. So if I were in your shoes it would be a crap shoot. Probably go with the pins. Make everything the right length and you're golden.
A speed part that dates at least back to 1947 is too modern for you and you compare them to an alternator? Normally I like pins, but the bones look better in this case.
I like bones but in my opinion the ones you have on the car are too short and the hairpins look outta place,,more like something that would be used on a full fendered car,,my 2 cents worth. BTW,the work on the car looks great! HRP
After careful consideration, looking at the pictures side by side and the overwhelming choice of knowledgable people whom I have the utmost respect for I have come to the conclusion I have only but one way to go. BONES! DEM BONES!
