Ran thru the decoder and comes up as: Y11 : RING GEAR, 10.50 IN., DANA (S.P.O ) But on my Dealer Invoice it states "VIP Plus Pkg" What would be the "Very Important Person Plus Package?" An extra $17.25 was paid for this option... Whoever ordered the car must not have been too important to be charged an extra $17.25, for something that seems trivial... John

It's got something to do with a roadside service package that was available back then. I think you got free towing if you broke down under warrenty.

Actually, it really stands for.

Y11=Sales, Special Extra Ornamentation (Gold)

The PHS documentation for my 88 Formula also listed the VIP option. It was as stated an optional package that offered roadside assistance and (i think) a loaner when your car was in for service.

I don't doubt that this RPO turns up different things, I beleive that it depends on the year. GM recycles

Darn, and I really wanted a Dana ring gear ...

thought it was interesting tho... One car got it, the other didn't Of course the one with Y11 was a special order...

Okfoz,

After I did my post, I got curious and started doing a search of various sites that list RPO codes. I ran into several that listed the Dana Ring Gear for Y11. I also ran into several that had several other descriptions for it. The description that I gave came out of a GM RPO code manual. I guess your best bet would be to go to your local dealership and give them the VIN and ask them what it is.

I know what it is on my car, Its spelled out on my dealer invoice ... I just happened to notice the discepancy... that's all...
