Chronometric tach

Post by Peter Pleitner » Mon Mar 11, 2002 10:18 am

Hi Whitworth Heads, I love my TC's tach so much that I'm interested in finding a chronometric tach drive I could adapt to the housing in one of my '58 Alfas. Do any of you know of someone who makes such tach drive mechanisms today? For general interest, what is the reduction ratio of the TC's tach drive gear box and are replacements chronometric mechanisms for the MG tach available anywhere? Cheers, Peter
