I have reproduced the Mk II alternator bracket due to the frequency of requests by my customers for an alternator conversion on their early Tigers. My alternator bracket is cast and precision machined off of my original bracket. The original bracket is Cast Iron; my reproduction is made from ZA-12 Zinc Alloy. ZA-12 Alloy has a higher tensile strength than 40kpsi cast Iron. Price $500.00 + shipping.
