Here's a Riviera cap GM part number # 1259878 What year and application? o No:

 

What is the group number on the box?

 

Gr.5.858

 

Center Cap?

 

my book only goes up to 1975 and i couldnt find it in there..... it is probably newer than 75 ... but then again, by book could be wrong. i have found several misprints and non-listings for parts in my the book.
rotsa ruk!! :Brow:

 

Looks like the center cap off a early 80s Riv with wire hubcats. I had one of those once and that's my guess. Does it have bolt holes in back to hold it onto the hubcap?

 

That is what I thought. No info here other than it is post 75. Mike may be right that it is 80s stuff. David can tell you exactly since he has accces to the recent stuff.

 

David who?????? I know it's a center cap I'm just wondering it's exact application? I thought it would fit the wire wheels we had but they are to small. As for a hub cap center it looks to small for that too. Thanks for all the help and i'll keep searching.

 

1978 with rpo code ph8

At least that is what my parts imager says

 

Thanks but what does that mean?

 

1259878

#1259878=1978 Riviera ( BZ ) body, center cap for the PH8 wheels.
PH8=wire spoke wheels 15x6. 1978 only, probably the 75th car.

Thanks again for the info I feel much better. Now who has a set of original wire wheels for 78 Riviera?

 

I actually

don't know.

 

I have a set and sure could use some center caps!!!

 

Are your rims for sale? I paid $200 for these awhile back.It wasn't what i needed but it was worth a try. + shipping.

 

I don't want to sell the wire wheels,too hard to find replacements. $200...was that for 4?
