I got the Smith's replica gauge set for my Sunbeam. 140 mph speedometer, 100-300 F water temp, volt meter, VDO type fuel gauge, 0-100psi
oil pressure and 8000rpm tach. The tach is mechanical so I was going to use that face on an electric tach or modify a Tbird Yblock tach drive distributor to work with the SB 260. Made in India but the quality looks as good as the original. I'll paint the needles flourescent orange. Anyway, here is the link, you would need a cable reverser behind the speedometer too. They have an anti clockwise tach also.
