I'm glad you took the time to do that, cuz I was gonna when I had a minute. But where did you get G80 as limited slip diff? G80 is usually Locking differential??? Is this specific for Burbs maybe??? Cuz his does not look like a gov-bomb at all and looks more like limited slip to me.

master rpo list from one of the gmfull size boards...

the hollander also has an rpo list.

 

[HotRodPC]

Damn, that looks complicated and easy to break.

Yours didn't nothing like that right??? It was all springs on both sides of the openings in the carrier???

OK, Cuz G80 is NOT a limited slip code. Its a locking diff code from what all I 've ever seen. But what is thid speedo delete and Gambia BS, was this to be a damn African truck or what? I'll be looking into that too. But I gotta get back outside working on my ATV that is for sale.

Yah, just springs between the spider gears.

I've been looking in to it too. Hollander says "Locking diff (limited slip)".

I told 89S that maybe his truck was destined for Gambia but was dropped off in Pennsyltucky instead.

That's what I am thinking too and why the speedo delete etc.

 

[RetroC10Sport]

I'm thinking the speedo delete stuff has to do with the cruise control.

 

[HotRodPC]

I was thinking that too or possibly the 4x4, cuz 4x4 speedo goes in the Tcase instead of Tmission.

 

[RetroC10Sport]

Or that too...

However, i don't believe my Blazer has those codes...I'll have to go dig out the build sheet.

[RetroC10Sport]

I found those codes for the speedo on a Camaro. So I vote no on the transfer case theory.

 

[HotRodPC]

yeah, I knew it was west coast Arfica 89S.

And it could be a OEM standard equipment GMC thing too that was deleted, cuz GMC comes with more standard equipment than Chev. And RPO codes are only for optional things. Like that Commitment Plus thing, that is GMC only deal. Its your first oil change free and something else too. Can't remember, but I know for a fact, Commitment Plus is GMC only. Not on Chevy or any other GM vehicle.

 

[RetroC10Sport]

Also found a few more trucks with the E6C Gambia code and no one seems to know.

Perhaps Greasedog can chime in here, he says he has the RPOs and such...

I didn;t, I never heard of that hole.
