Aluminum Turning Fin - Fastener Type

[hallmj5]

Hi Everyone,

I have an aluminum turning fin that I want to install on a 1952 Swift A/B hydro and I'm having trouble finding the proper fastener type to anchor the fin. What metal fastener material would you recommend to avoid galvanic corrosion caused by dissimilar metals? Much appreciated!
