I have smaller wheels so the speedo is off. I'm trying to find speedo gears (if available) but I can't figure what trans model number. Thanks in advance. | | | | | Joined: May 2001 Posts: 7,438 Extreme Gabster | | Extreme Gabster Joined: May 2001 Posts: 7,438 | | | | | | Joined: Apr 2016 Posts: 22 'Bolter | | 'Bolter Joined: Apr 2016 Posts: 22 | Thank you for the reply and info.

I looked at the trans and after removing the speedo cable it looks like a metal nut in the trans, maybe a 19mm or bigger. I've seen that they sell the all metal ones that look like it but not finding in 22 tooth or a lil bigger. | | | | | Joined: Mar 2004 Posts: 6,236 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 6,236 | Why don't you calculate the speed difference and install a ratio adaptor in the cable? They are on eBay all the time.

The GM Herritage center is a great resource.
