Thank you for being here!

Wow very cool build. You might have the only limited slip equipped V6 C10 with a 4 speed still in existence. I’m always amazed at the number of SPID’s I look at, and almost never see the G80 option. Which seems like a no brainer, especially on a 2wd truck. Never understood why people didn’t get them.

Could you have gotten a factory tach with this combo?

Being from a more performance oriented family, and driving 2wd trucks exclusively at the time here in Michigan, my dad and I always ordered the G80 rear axle.

Still do.

But I recognize we are probably outliers.

Yes –

And no.


Yes – normally. You could get any option content with the MY6 that could be had with any other manual trans (M20, M62/M64). So that would include the tach cluster, and cruise control, etc.

The problem was this: recall that my trans was stop ordered briefly during the ordering process. When they did that the engineering specifications team stripped all the MY6 associated RPO content out of the VDS* (as is their custom). When the stop order was lifted, via the temporary deviation, they had to manually add all that stuff back in – but in the confusion they missed U18 (Tach cluster) and K34 (cruise). As a result when I tried to order my truck with those two options the order got bounced.

It ended up getting built without.

I procured a tach cluster and installed that after the fact. If you were to remove the cluster today you would find some hard wires behind the cluster still that I needed to add in order to make it work.

I recall for the cruise set up I ordered a service kit over the counter. It was packaged and had everything I needed to add cruise (including instructions).

You could get anything over the counter at Milford if it had a GM part number.
